It is fairly normal for dogs to get a case or diarrhea. Because of the human concern for their best friends, they tend to rush to the vet whenever they see signs of diarrhea. Many times this does not require a veterinary visit. In fact if the vet prescribes antibiotics, the dog may be taking medication unnecessarily and could hurt him. The diarrhea may pass on its own and will not need a visit to a professional. If the diarrhea becomes chronic, then it could cause or be indicative of more serious problems and be harder to deal with.
Acute diarrhea normally has a very sudden start and stays around for a few days to two weeks. This can normally be taken care of at home. In order to know when to take him to the vet, there are a few things you should look for. How is he acting? If he is acting normal, eating, drinking and playing as he always does, the diarrhea is not a huge problem. If he seems to have less energy or is not eating or drinking, then a visit to the vet may be in order. He may say the dog is fine, but the visit will not hurt any.
Normally diarrhea is caused by the consumption of some kind of toxin that the body is trying to get rid of. The dog may have eaten or drank something that is poisonous or does not work well with the dog’s digestive track. You should check around the house and the dog’s living area to see if he may have gotten into anything that may have caused it. If you do go to the vet you may want to ask if any household items cause diarrhea in pets and put those things away safely.
