Fido can certainly come down with the occasional case of nausea. Lots of things can cause it, such as food allergies, parasites, infections, foreign objects and overfeeding. In some cases, nausea might call for a drive to the doctor.
Symptoms
Nausea may see your pup licking his lips, panting, swallowing excessively, drooling and being less active than usual. Vomiting often accompanies nausea, but not always -- sometimes your pup will come down with an upset tummy that doesn't cause him to empty its contents onto your floor. Diarrhea is also a common symptom.
What to Do
If Fido seems ill for longer than 24 hours, vomits more than once, has frequent diarrhea or experiences other symptoms, such as dehydration and weakness, call your vet right away. Withholding food for 12 to 24 hours and reintroducing it slowly afterward if he vomits only once, or feeding him rice and boiled chicken for a day or so if he has one bout of diarrhea, is completely fine and helpful. If those remedies don't help, or if they exacerbate the problem, it's time for a vet visit. Veterinarian Jennifer Coates, in her PetMD blog, warns against trying home remedies and instead suggests talking with your vet if Fido's a puppy or senior dog.
