Gastroenteritis is the inflammation of the stomach and intestines and can cause symptoms such as vomiting, diarrhoea, reduced appetite and abdominal discomfort.
There are a lot of possible causes, including eating something unusual, a sudden change in diet, infections, parasites, stress or other underlying health problems.
Some cases are mild and resolve by themselves, but others can become serious quickly, especially if your dog is losing a lot of fluids.
You should contact us promptly if your dog:
👉 Is vomiting repeatedly or cannot keep water down
👉 Has blood in their vomit or diarrhoea
👉 Seems very lethargic, weak or unusually quiet
👉 Has a painful, swollen or bloated abdomen
👉 Shows signs of dehydration, such as dry gums or reduced urination
👉 May have swallowed a foreign object, toxin or something they shouldn’t have
👉 Has severe symptoms, that are worsening or not improving
👉 Is a young puppy, elderly dog or has an existing health condition
Even what looks like a simple stomach upset can sometimes have a more serious cause, so if you’re worried about your dog, or their symptoms seem out of the ordinary, speak to us for advice.
