Dogs can experience stomach upset just like humans. A dog that is sick with a stomach virus is just plain miserable, and you want to make him as comfortable as possible. Many dogs have sensitive digestive systems, and some breeds are more prone to gastric upset than others. Symptoms of a stomach virus can be very similar to symptoms of other, more serious conditions, so it is best to seek medical attention for your pet for proper diagnosis and treatment.
Bloating and Flatulence
Bloating and flatulence can often be early symptoms of stomach virus in dogs. Flatulence may continue throughout the course of the virus.
Vomiting and Diarrhea
Vomiting and diarrhoea are classic signs of intestinal distress. The primary danger that accompanies diarrhoea and vomiting is that dehydration can occur. It is important to try and keep the dog hydrated.
A dog that is suffering from a stomach virus will display symptoms of lethargy and fatigue. He will likely just lie around and show no interest in his usual activities.
Loss of Appetite
Loss of appetite is a common symptom in illness that causes stomach upset. A dog with stomach flu doesn't have an appetite and won't feel like eating.
A dog can experience the discomfort of intestinal cramping just as humans do, although she cannot tell you that she is in pain. She may whine or whimper and display other behaviour that expresses the fact that she is experiencing abdominal pain.
It is best to call your veterinarian if your dog displays any of these symptoms, since several health conditions are accompanied by similar symptoms. Vomiting, diarrhoea and other symptoms of abdominal distress could be signs of serious disease such as parvovirus or distemper. It's better to err on the side of safety even if the condition is mild.
