Dog Food for Acid Reflux
What the Merck Veterinary Manual says about feeding a dog with esophagitis from acid reflux - soft food, low in fat and fiber, small frequent meals - the signs to watch for, and two wet low-fat veterinary diets compared on what their makers publish. A reading guide, not veterinary advice.
AI illustration This is a reading guide to published veterinary information and to what makers state on their own pages. Regurgitation, drooling and trouble swallowing can come from several problems of the esophagus, including a swallowed object, so a dog with these signs needs a vet to find the cause.
The short answer: soft, low-fat food in small, frequent meals, plus whatever medicine your vet prescribes. In the Merck Veterinary Manual, inflammation of the esophagus (esophagitis) is usually caused by a swallowed foreign object or by acid flowing back up from the stomach. When it causes signs, your vet may recommend a diet of soft food, low in fat and fiber, fed in small, frequent meals.
Signs and Treatment
Merck notes that mild inflammation may cause no visible signs and often needs no treatment. When signs appear, they include:
- regurgitation and drooling
- repeated swallowing
- pain and depression
- lack of appetite or trouble eating
- stretching out the head or neck
When acid reflux is the cause, drugs that reduce stomach acid can bring relief, and other medicines tighten the muscle at the lower end of the esophagus so less acid escapes. In severe cases, a feeding tube into the stomach lets the esophagus rest.
Regurgitation or vomiting? Merck describes regurgitation as food or liquid coming back up before it reaches the stomach. It happens passively, without the heaving of vomiting. Our guide to why your dog keeps throwing up explains the difference.
Two Wet Low-Fat Diets Compared
These are wet versions of the low-fat digestive diets in our pancreatitis guide. Wet fits the “soft food” part of Merck’s description.
| Diet (wet) | Fat | Fiber | Energy | AAFCO statement | Source |
|---|---|---|---|---|---|
| Hill’s Prescription Diet i/d Low Fat, Original Flavor | 7.8% of dry matter | 2.8% of dry matter | 328 kcal per can | Feeding tests, adult maintenance | Hill’s |
| Purina Pro Plan Veterinary Diets EN Gastroenteric Low Fat | 1.35% min, 4.0% max, as sold (moisture 76% max) | 2.0% max, as sold | 363 kcal per can | Adult maintenance | Purina |
How we put this together. Two wet low-fat veterinary diets, compared on what each maker states on its own page, checked on 26 October 2026. Hill’s gives nutrients on a dry-matter basis, without water, and Purina gives a range for the food as sold, so the numbers do not line up directly. Both are veterinary diets: Purina’s page says “use only as directed by your veterinarian”. That is why there are no shop links. We have not fed them, and neither maker markets these foods specifically for reflux. They appear here because they match the low-fat, soft description in Merck.
At Home
- Small, frequent meals, as Merck describes, rather than one large one.
- Follow the medicine schedule your vet gives.
- Watch for regurgitation, pain on swallowing or weight loss, and report them.
