Please seek veterinary attention immediately. An expanded stomach could be a sign of bloat, which is a life-threatening condition. A veterinarian can diagnose the issue and provide the appropriate treatment.
Here's why you should go to the vet:
* Bloat can be fatal: It's a serious condition that can lead to organ damage and death.
* Veterinarians are trained to diagnose and treat bloat: They can determine the cause of the expanded stomach and provide the right treatment, which may include surgery.
* Time is crucial: The sooner your dog gets veterinary care, the better their chances of survival.
In the meantime, do not try to treat your dog yourself. Avoid giving them any food or water, and keep them calm.
Please call your veterinarian or take your dog to an emergency veterinary clinic right away.
