What Is Entyce and What Does It Treat?
Entyce is a prescription medication used to stimulate appetite in dogs. Its active ingredient is capromorelin, and it is FDA-approved specifically for appetite stimulation in dogs — making it one of the few purpose-built appetite stimulants for canine patients.
A dog that will not eat is a real and common problem. Inappetence (a poor or absent appetite) can accompany many situations — recovery from illness or surgery, chronic diseases such as kidney disease or cancer, the side effects of other medications, or simply a dog that has become a reluctant eater. Whatever the cause, a dog that does not eat enough loses weight, loses strength, and heals more slowly.
Entyce works by mimicking a natural hormone called ghrelin — often nicknamed the “hunger hormone.” Capromorelin is a ghrelin receptor agonist: it binds to the same receptors that ghrelin does, sending the brain a “feel hungry” signal and prompting the dog to eat. It also acts on the pituitary gland to increase growth hormone, which supports weight gain.
It is important to understand the role Entyce plays. It is an effective tool for getting a dog eating again, but it treats the symptom, not the cause. A poor appetite is often the first visible sign of an underlying illness, so Entyce should be used alongside a veterinary investigation into why the dog stopped eating — not as a substitute for one.
Entyce is a prescription medication. Use the calculator above to understand the dose, but a veterinarian must prescribe it and assess your dog. For more, see PuppaDogs’ guide to Entyce and Elura for dogs.
How the Entyce Dosage Calculator Works
Entyce dosing is simple and based purely on body weight. The calculator:
- Applies the standard 3 mg/kg once-daily dose.
- Converts it into the volume of oral solution to give from the 30 mg/mL bottle.
- Flags health conditions that need veterinary caution.
Enter your dog’s weight, tick any health considerations, then press Calculate Dose.
How Entyce Doses Are Calculated for Dogs
The Standard Dose
The FDA-approved dose of Entyce for dogs is:
3 mg/kg of body weight (1.4 mg/lb), given by mouth once daily.
Entyce is supplied as a 30 mg/mL oral solution, which makes the volume easy to work out:
Volume = 0.1 mL per kilogram of body weight.
So a 10 kg (22 lb) dog needs about 1 mL once daily, and a 30 kg (66 lb) dog about 3 mL once daily.
A Liquid That Must Be Measured Accurately
Entyce comes as a flavoured liquid with a dosing syringe. Insert the syringe into the bottle, invert the bottle, withdraw the correct volume, and give it directly into the dog’s mouth. Accurate measurement matters — use the supplied syringe rather than guessing.
Entyce Dosage Chart for Dogs
This chart shows the once-daily 3 mg/kg dose. It is a reference only — your veterinarian’s prescription takes priority.
| Dog weight | Dose (3 mg/kg) | Volume (30 mg/mL) |
|---|---|---|
| 5 kg (11 lb) | 15 mg | ~0.5 mL |
| 10 kg (22 lb) | 30 mg | ~1.0 mL |
| 20 kg (44 lb) | 60 mg | ~2.0 mL |
| 30 kg (66 lb) | 90 mg | ~3.0 mL |
| 40 kg (88 lb) | 120 mg | ~4.0 mL |
How to Give Entyce to Your Dog
- Once daily, at roughly the same time each day.
- Measure with the supplied syringe and give the liquid directly into the mouth.
- Give it a little before offering food — Entyce stimulates appetite, so a dose ahead of mealtime makes sense.
- Store as directed on the label and check the in-use shelf life of the opened bottle.
- Missed dose: give it when you remember, or simply give the next scheduled dose — never double up.
Side Effects and Safety
Entyce is generally well tolerated. The most commonly reported side effects are mild and digestive:
- Drooling (hypersalivation) — often seen shortly after dosing
- Vomiting
- Diarrhoea
- Occasionally, lethargy
These are usually mild. Tell your veterinarian if they are marked or persistent.
When to Use Caution
Use Entyce with veterinary caution in dogs that:
- Have liver disease — capromorelin is processed by the liver
- Are pregnant, breeding or nursing — safe use has not been established
- Take other medications — capromorelin affects cortisol and growth-hormone levels and may interact with some drugs
Always give your veterinarian a full health and medication history.
Why the Underlying Cause Matters
This point is worth repeating because it is the most important one. A dog’s appetite is a sensitive barometer of health. When a dog stops eating, it is often telling you something — it may be nauseated, in pain, fighting an infection, or developing a chronic disease. Entyce can override that “off” switch and get the dog eating, which is genuinely valuable for recovery and quality of life. But if the appetite loss is caused by, say, kidney disease or a painful condition, the real problem still needs diagnosing and treating.
That is why Entyce works best as part of a plan: your veterinarian uses it to support nutrition and recovery while also investigating and addressing whatever caused the inappetence in the first place. Where nausea is part of the picture, an anti-nausea medication may be combined with it; where another type of appetite support is preferred, your vet might discuss alternatives such as mirtazapine.
Treatment Duration
How long a dog stays on Entyce depends entirely on the situation. For a dog recovering from a short illness or surgery, it may be needed for only a few days to a couple of weeks. For a dog with a chronic condition, it may be used longer-term under veterinary supervision. Your veterinarian will decide based on your dog’s weight, body condition and the underlying diagnosis.
Conclusion
Entyce (capromorelin) is a safe, effective, FDA-approved appetite stimulant for dogs, dosed simply at 3 mg/kg (0.1 mL/kg of the 30 mg/mL solution) by mouth once daily. The calculator above gives you that dose and the volume to measure. It can make a real difference to a dog that has stopped eating — supporting weight, strength and recovery — but it should always be used under veterinary direction and alongside a proper investigation of why the appetite was lost in the first place.
Frequently Asked Questions
How much Entyce do I give my dog?
The FDA-approved dose of Entyce (capromorelin) for dogs is 3 mg/kg of body weight, given by mouth once daily. Because Entyce is a 30 mg/mL oral solution, that works out to 0.1 mL per kilogram – about 1 mL for a 10 kg dog and 3 mL for a 30 kg dog. Always confirm the dose with your veterinarian.
How long does Entyce take to work?
Entyce often works quickly. Because it mimics the hunger hormone ghrelin, many dogs show an improved appetite within the first day or two of starting it. It is usually given a little before offering food so the appetite stimulation lines up with mealtime.
What are the side effects of Entyce in dogs?
Entyce is generally well tolerated. The most common side effects are mild and digestive – drooling, vomiting or diarrhoea, and occasionally lethargy. These are usually mild; tell your veterinarian if they are marked or persistent.
Why won’t my dog eat, and will Entyce fix it?
Entyce stimulates appetite, but it treats the symptom rather than the cause. A poor appetite can be the first sign of an underlying problem such as nausea, pain, infection or chronic disease. Entyce can get your dog eating again to support recovery, but your veterinarian should also investigate and treat whatever caused the appetite loss.
Can Entyce be given long term?
Yes, Entyce can be used short-term for recovery from a brief illness or surgery, or longer-term under veterinary supervision for dogs with chronic conditions. How long a dog stays on it depends on the underlying cause of the inappetence and the dog’s body condition, which your vet will monitor.
Should Entyce be given with food?
Entyce is usually given a little before offering a meal, so its appetite-stimulating effect coincides with mealtime. It is measured with the dosing syringe supplied with the bottle and given directly into the mouth. Follow your veterinarian’s specific instructions.
