Composure (generic: colostrum calming complex + L‑theanine + thiamine) is an over‑the‑counter calming behavioral supplement for dogs. Brand names you may see include Composure and Composure Pro (the Pro version also adds L‑tryptophan). It’s designed to help “take the edge off” without sedation.
Top uses your team will hear: short‑term stress around thunderstorms/fireworks, travel or vet/grooming visits, and mild separation‑related stress. It’s for dogs only. If owners ask about how or when to use it with their pet’s plan, your veterinarian can discuss timing, product choice (standard vs. Pro), and whether a different approach is needed.
Note: VetriScience has rebranded the Composure line as Calm & Confident with the same formulas. If a client mentions that name, it’s the same product family. If a dog has severe panic, worsening behavior, or any concerning reactions (extreme lethargy, vomiting, wobbliness, facial swelling, breathing trouble), escalate to the veterinarian immediately; use emergency care for collapse or trouble breathing.
Front desk script: Composure is an over‑the‑counter calming supplement for dogs that combines colostrum proteins, L‑theanine, and vitamin B1 to help with stress from things like storms, travel, or vet visits. Composure Pro is the veterinary‑strength version. Our veterinarian can advise if this is a good fit for your dog and how it would fit into their behavior plan. If your dog has severe panic or you notice wobbly walking, vomiting, or trouble breathing, please call us right away or go to emergency care for severe signs.
- What is Composure and what does it do? Composure (also sold to clinics as Composure Pro) is a calming supplement with L‑theanine, thiamine (vitamin B1), and a milk‑derived colostrum complex. It’s intended for mild, situational stress (vet/groom visits, travel, storms) and is not a prescription sedative. Manufacturer‑sponsored studies report effects in many dogs within about 30 minutes that can last around 4 hours, but individual response varies; some pets need daily use alongside training. Your veterinarian can discuss whether a supplement, behavior plan, or a prescription medication is the best fit for your dog’s anxiety.
- Will it make my dog sleepy or change their personality? It’s designed to promote calm without sedation; most dogs stay alert. Mild stomach upset can occur with oral supplements, and rare sensitivities are possible—especially in pets with milk allergy, since colostrum is milk‑derived. Seek emergency care now for facial swelling, hives, collapse, trouble breathing, or repeated vomiting/diarrhea with lethargy; otherwise contact the clinic same day for guidance.
- Can I use it with my dog’s other medications or health issues? Always check with the veterinarian first. L‑theanine can lower blood pressure, so extra caution is needed if a dog is on antihypertensive meds. Use caution if your dog has a known milk allergy/sensitivity. Safe use in pregnant or breeding animals has not been established on the manufacturer’s label—defer to the veterinarian.
- What if I miss a dose or my dog ate extra? If you miss a dose, give it when remembered or skip if it’s close to the next scheduled time—don’t give two doses at once. If you suspect an overdose or your dog isn’t acting right, call us immediately; if we’re closed, go to an emergency hospital.
- Is Composure the same as Calm & Confident? VetriScience rebranded Composure products in 2024–2025; you may see the same formulas in new packaging and names (e.g., “Veterinary Strength Calm & Confident” for Composure Pro). If owners are unsure which bag they have, ask them to read the ingredient list—L‑theanine, thiamine, and colostrum complex indicate the classic formula.
Front desk script: Composure is an over‑the‑counter calming supplement, not a sedative. Many dogs show a calming effect within about 30 minutes, but every dog is different. Because it can interact with some conditions and meds, and colostrum is milk‑derived, let me check with the veterinarian before you use it alongside other treatments. If you ever see facial swelling, hives, trouble breathing, collapse, or repeated vomiting with lethargy, please seek emergency care right away. For ongoing anxiety like separation issues or noise phobia, our veterinarian can discuss a full behavior plan and whether a prescription option is more appropriate.
Most owners report no side effects with Composure. When they do call back, the most common comments are that the dog seems extra calm for a few hours or has mild tummy upset (soft stool, gas, a single vomit, or a brief decrease in appetite). These effects are usually short-lived and are consistent with what can occur with oral supplements such as L‑theanine, colostrum, and B‑vitamins. True drowsiness is not expected, but some pets may act more relaxed than usual. Dogs with milk sensitivity can rarely show GI upset or skin signs due to the colostrum component.
Ask owners to call the clinic the same day if: vomiting or diarrhea occurs more than twice or lasts beyond 24 hours; appetite is poor for more than a day; new hives, facial/lip swelling, or itchiness appear (possible allergy); the dog seems unusually weak, wobbly, or collapses—especially if also taking blood‑pressure medications (rare interaction reported for L‑theanine). Treat trouble breathing, facial swelling with breathing changes, collapse, seizures, or any rapidly worsening signs as an emergency now. Your veterinarian can discuss whether symptoms are related to the supplement and what to do next.
Front desk script: Thanks for calling about Composure. Mild stomach upset or a dog acting extra relaxed for a few hours can happen with supplements and often passes quickly. If your dog has vomiting or diarrhea more than twice, isn’t eating for a day, develops hives or facial swelling, or seems very weak or wobbly—please let us know today; if there’s trouble breathing or collapse, go to the nearest emergency clinic now. I’ll note your concerns and have our veterinarian review and advise next steps.
Composure is an over‑the‑counter calming supplement most commonly given as soft chews for dogs; mini chews and multiple flavors exist. There is also a veterinary‑line product (Composure/Calm & Confident Veterinary Strength) and a veterinary‑only liquid option for pets that won’t take chews. The manufacturer notes Composure is now sold as “Calm & Confident,” but it is the same trusted formula family; clinics may stock either name. Chews can be given directly like a treat, and the liquid can be given by mouth or placed in the bowl at meal time. Giving doses with a small meal or snack is acceptable and may reduce stomach upset; ask the veterinarian about any medication/supplement interactions for that pet. [Sources: below]
If a dog won’t take the chew: try breaking it into smaller pieces and mixing with a small amount of food, or hiding it in a soft, strong‑smelling treat (peanut butter, cheese, commercial pill treats). Keeping the bag sealed and fresh can help palatability. If acceptance is still poor, ask about trying a different flavor or the veterinary‑only liquid formulation; your veterinarian can discuss which option fits that patient. [Sources: below]
Troubleshooting GI upset: if a dog vomits after a dose, advise the owner to give the next dose with a small meal or treat. If vomiting occurs more than once, if there is diarrhea, lethargy, tremors, or if you see blood, escalate to a same‑day veterinary assessment; repeated vomiting, collapse, or severe weakness warrant urgent/emergency care. The product label also advises administering during or after eating to reduce GI upset; your veterinarian can advise whether to continue and discuss alternatives (including liquid formulations or, when appropriate, compounding through a pharmacy). [Sources: below]
Front desk script: This supplement comes as soft chews and also as a veterinary‑only liquid if chews are hard to give. It’s fine to give it with food; in fact, giving it during or after a meal may help prevent an upset stomach. If your dog won’t take the chew, you can crumble it into a small amount of food or hide it in something soft like peanut butter or a pill treat. If your dog vomits more than once after a dose or seems very unwell, please call us the same day; if there’s repeated vomiting, collapse, or blood, go to the nearest emergency clinic. Your veterinarian can also discuss flavor options or switching to the liquid.
Composure (and Composure Pro) is a non‑prescription calming supplement for dogs. Treat refills like a retail purchase: no prescription or doctor approval is needed for pick‑up or shipment if your clinic stocks it. A recheck exam is not required solely to purchase this supplement; however, if the caller reports that the dog’s anxiety is worsening or not improving, offer an appointment—your veterinarian can discuss behavior options or alternative therapies.
Call handling: confirm the exact product and version (Composure vs. Composure Pro; note many listings now appear under the rebranded name “Calm & Confident”), package size/count, flavor, pet’s name, and preferred pick‑up/shipping method. If in stock, provide same‑day or next‑business‑day pick‑up; if out of stock or special‑ordering, advise typical turnaround of 1–3 business days (per clinic policy). Typical repurchase timing varies by package size and household use; many clients choose 30–90‑day auto‑ship intervals offered by suppliers. For online pharmacies, this item is over‑the‑counter and usually does not require clinic authorization; clients can buy directly from your clinic’s online store or reputable retailers. If an external pharmacy mistakenly sends a prescription request, respond per clinic policy (e.g., “OTC supplement—no authorization required”) and inform the client of purchase options.
Escalate the call if the pet has severe or escalating anxiety (panic, self‑injury, can’t settle for hours) or if new concerning signs appear after giving any supplement (e.g., tremors, collapse). Mark as same‑day triage and involve a veterinarian immediately; advise the caller to seek urgent/emergency care if the pet is actively in distress.
Front desk script: Good news—Composure is an over‑the‑counter calming supplement, so we can set it aside for you without a prescription. Do you want the standard Composure or the veterinary version (often shown online now as “Calm & Confident”), and what bag size would you like? If it’s in stock, you can pick it up today; if we need to order it, it typically arrives in 1–3 business days. If your dog’s anxiety has gotten worse or you’re seeing alarming signs like panic or tremors, I’ll flag this as same‑day for a veterinarian to advise right away.
Escalate to the medical team immediately for any signs of a severe allergic reaction after Composure: sudden hives or raised welts, swelling of the face/muzzle/around the eyes, vomiting with facial swelling, trouble breathing, collapse, or sudden weakness—treat these as an emergency. Note that some Composure products contain milk-derived colostrum and may include chicken flavoring and soy; dogs with food allergies can react. Hives on the face or around the throat can progress to airway swelling and require urgent care.
If a dog chewed into the container or ate far more than intended, connect the caller with a vet/tech right away. Have the product package handy (to confirm ingredients), when it was eaten, and the dog’s approximate weight. Seek same-day help for repeated vomiting or diarrhea, extreme sleepiness, stumbling/unsteadiness, or difficulty rousing—especially if the dog also takes blood-pressure–lowering medications, since L-theanine can lower blood pressure. Your veterinarian can discuss whether it is appropriate to continue or adjust calming supplements after the pet is stabilized.
Front desk script: Because you’re seeing swelling/hives or any trouble breathing, this could be a severe allergic reaction. This is an emergency—I’m getting a veterinarian or technician on the line now. If your dog chewed into the Composure and ate a large amount, please stay on the phone while I connect you with our medical team; have the package with ingredients nearby. If your dog is very sleepy, wobbly, or hard to wake, we should see them today—I’ll transfer you to a technician for immediate guidance.
Composure is a calming supplement for dogs with L-theanine, thiamine (vitamin B1), and a colostrum calming peptide; some versions (Composure Pro) also include L-tryptophan. Published interaction data for these nutraceuticals are limited. Known cautions include: L‑theanine may lower blood pressure (flag if the pet is on antihypertensives), and thiamine can interact with amprolium or fluorouracil. If owners mention they are using the Pro version that contains L‑tryptophan, alert the veterinarian to any serotonergic prescriptions on the patient’s list. ([vcahospitals.com](https://vcahospitals.com/know-your-pet/l-?utm_source=openai))
Commonly co-prescribed behavior medications with calming supplements include trazodone, gabapentin, clonidine, dexmedetomidine (Sileo), and longer-term agents like fluoxetine or clomipramine. The main interaction categories to flag are: additive drowsiness/sedation when combined with other CNS depressants; possible additive blood‑pressure lowering (e.g., L‑theanine with antihypertensives or clonidine); and potential serotonergic load if a product contains L‑tryptophan and the pet is also on SSRIs/SARIs/TCAs/MAOIs or tramadol—your veterinarian can discuss risk and monitoring. ([vcahospitals.com](https://vcahospitals.com/know-your-pet/pre-visit-pharmaceuticals-for-dogs?utm_source=openai))
OTC add‑ons owners often give alongside calming chews: diphenhydramine (Benadryl) and melatonin (both can add sedation and interact with other sedatives), and CBD products (may increase sedation when combined with other calming meds). Urgent red flags to escalate immediately: severe or unexpected sedation, collapse, extreme weakness/ataxia, very slow or very fast heart rate, or signs suggestive of serotonin syndrome (agitation, tremors, panting, vomiting/diarrhea, fever). If any of these occur, direct the owner to emergency care now; otherwise, schedule a same‑day veterinary review of all medications and supplements. ([vcahospitals.com](https://vcahospitals.com/valley-vet/know-your-pet/diphenhydramine?utm_source=openai))
Front desk script: Thanks for calling about Composure. So I can keep your pet safe, can I read back your dog’s full medication and supplement list, including any OTC items like Benadryl, melatonin, or CBD, and any blood‑pressure meds? Some versions of Composure include L‑tryptophan, so I’ll also note if your dog is on fluoxetine, trazodone, clomipramine, tramadol, or similar meds for our doctor to review. I’m flagging this for the veterinarian to advise you on combinations and monitoring. If your dog seems extremely sleepy, wobbly, collapses, or shows agitation, tremors, vomiting/diarrhea, or fever, please go to the nearest emergency clinic now.
Storage: Keep Composure/Composure Pro chews in a cool, dry place, out of direct sunlight. Refrigeration is not required (and not recommended) unless the package specifically says so. When stored properly, the product remains shelf‑stable through the printed expiration date even after opening; keep the bag or container tightly closed between uses. If the product smells rancid or looks discolored, do not dispense and contact the manufacturer or your veterinarian for guidance. Your veterinarian can discuss what to do if you have concerns about product quality or storage conditions.
Child/pet-proofing: Treat-like chews are enticing. Store up high in a closed cabinet or a latched, airtight container. Labels state to keep out of reach of children and animals; in case of accidental overdose, contact a health professional immediately. If a dog gets into a large amount at once or shows concerning signs (e.g., repeated vomiting, tremors, severe lethargy/collapse), seek emergency veterinary care now or contact a poison control resource. Your veterinarian can advise on next steps after any accidental ingestion.
Disposal: For expired or unneeded chews, use a community medication take‑back program when available. If no take‑back is available, do not flush; mix the chews with an unappealing substance (e.g., used coffee grounds or cat litter), seal in a bag or container, and place in household trash. Secure trash so pets can’t “dumpster dive.” Your veterinarian or local pharmacy can help locate take‑back options.
For Composure (colostrum calming complex/L‑theanine/thiamine), there is no standard lab work or blood monitoring required in healthy dogs. Monitoring is mainly at home: ask owners to note any changes in behavior (calmness around known triggers) and any stomach upset such as soft stools or vomiting. Your veterinarian can discuss if extra monitoring is needed for pets with other medical conditions or those taking additional medications.
Scheduling: follow the veterinarian’s plan noted in the record. If no timeframe is documented, check with the doctor before booking a recheck. Owners should contact the clinic if there is no improvement by about 60 days or if signs worsen, per L‑theanine supplement guidance. Keep a brief “stress/response” log to review at the recheck so the doctor can judge benefit and next steps.
Escalation: if the pet shows possible allergic reaction signs (facial swelling, hives, trouble breathing) or has collapse or repeated vomiting/diarrhea after a dose, instruct the owner to stop the supplement and seek immediate veterinary care or go to the nearest emergency clinic. Your veterinarian can advise on next steps after any urgent event.
Front desk script: This calming supplement usually doesn’t need routine bloodwork. The doctor will set the follow‑up plan; if it’s not in the chart, I’ll confirm timing with them. Please keep a simple log of your dog’s stress triggers, behavior changes, and any tummy upset so we can review at the recheck. If you see facial swelling, hives, trouble breathing, collapse, or repeated vomiting/diarrhea after a dose, stop the supplement and go to the nearest emergency clinic right away, then let us know.
Composure (Composure Pro) is a non‑prescription calming supplement for dogs made by VetriScience. It contains a colostrum‑based calming complex, L‑theanine, and vitamin B1 (thiamine). The manufacturer reports it supports calm behavior without sedation and may start working in about 30 minutes, with effects lasting up to 4 hours. Your veterinarian can advise whether this supplement is appropriate for an individual dog and review potential interactions with other medications or health conditions.
Safety notes for front desk: supplements can still cause side effects. L‑theanine and other oral supplements may cause mild gastrointestinal upset or sensitivities in some pets, and caution is advised in dogs with severe behavior disorders or on blood‑pressure–lowering drugs; the veterinarian should guide any use. If a caller reports collapse, trouble breathing, facial swelling, severe vomiting/diarrhea, tremors, or unresponsiveness after any product, direct them to the nearest emergency hospital immediately; otherwise, route the call to the medical team.
Phrases to avoid: “It’s harmless,” “Start/stop it on your own,” “Give X amount,” or promising that it will cure anxiety. Instead use neutral language (e.g., “It’s an over‑the‑counter calming supplement; our veterinarian can discuss if it’s a good fit and advise on dosing and monitoring.”).
Front desk script: Thank you for calling [Hospital Name], this is [Your Name]—how can I help you today? Composure is an over‑the‑counter calming supplement for dogs with L‑theanine, a colostrum‑based calming complex, and vitamin B1; the maker notes it may start working in about 30 minutes and can help with mild, situational stress. Because supplements can interact with other products and aren’t right for every dog, our veterinarian can discuss whether it’s appropriate and provide dosing guidance—I can’t advise on dosing or starting/stopping over the phone. If your dog has collapse, trouble breathing, facial swelling, tremors, or severe vomiting/diarrhea, please go to the nearest emergency hospital now; otherwise I’ll connect you with our medical team. Would you like me to schedule a quick consult or have the doctor call you back?
