Why repeated diet changes can make things worse
Abrupt switches can trigger gastrointestinal upset and make it harder to identify what the dog actually tolerates. Unless your veterinarian recommends otherwise, transitions are usually made gradually.
What types of diets may be considered?
Depending on the problem, a veterinarian may consider a highly digestible diet, a fat-modified diet, a hydrolyzed-protein diet or a novel-protein elimination diet. These are not interchangeable; the choice should match the diagnostic question.
What about homemade food?
Plain chicken and rice may be used short-term in selected situations but is not a complete long-term diet. Home-prepared diets intended for ongoing feeding should be formulated to meet nutrient requirements. See our guide to homemade diets for dogs.
When should I call the veterinarian?
Seek care for repeated vomiting, persistent diarrhea, weight loss, blood in stool or vomit, abdominal pain, poor appetite, dehydration or symptoms that keep returning despite diet changes.
