The most common signs are vomiting, diarrhoea, flatulence, lethargy and weakness. If your dog has diarrhoea or is vomiting, they may become severely dehydrated, always get in touch with your vet as soon as possible if you see these signs.
Gastroenteritis is common and normally clear up within a few days. However, some dogs may need long-term management because they have regular or permanent digestive problems.
Your vet will want to determine the cause and will commonly ask if your dog has ingested any foreign objects or what their diet is and if there has been a change.
Your vet may take a blood sample to perform a number of tests to check vital organ function, sugar levels and electrolyte levels to ensure your dog isn’t dehydrated. X-rays of the abdomen may also be required if a foreign body or obstruction is suspected.
If your dog is dehydrated they may need to be hospitalised and be given fluids via a drip and medication to protect the stomach and to stop any vomiting.
