A good diet and plenty of exercise are important to a dog’s health, but they can’t make a dog totally immune to illness. Early detection is the key to helping your dog overcome any health problem. If your pet’s stools become very loose, or you notice a marked decrease in your dog’s appetite and/or that she is very lethargic, she may just have a short-term “bug.” On the other hand, if any symptoms continue for more than a few days, you should have your veterinarian examine her for parasites and infections.

Diarrhea is a common symptom in dogs, especially puppies. It can be triggered by stress or a sudden change in food, but also by a virus, bacteria or parasites. Diarrhea causes dehydration, which can be deadly to dogs. It is extremely dangerous in puppies, because they dehydrate faster than mature dogs. If your dog has diarrhea for more than a day, contact your veterinarian for further instructions. You will probably be asked to collect a sample and bring it in so they can examine it to determine the cause and proper treatment.
