If your German Shepherd is having occasional upset stomach or diarrhea then you should give your vet a call. Your pup may be ill or he may just have an upset stomach. Your vet can help determine the cause. In some cases, German Shepherds and other canines simply need a probiotic supplement to help support the digestive system. Probiotics are the good bacteria that live in your dog’s digestive tract. Many dogs can benefit from a probiotic supplement as they not only aid digestion, but also help build up the immune system. Some experts have found that probiotics can be used to treat diarrhea, irritable bowel, and intestinal inflammation. They may also be used to prevent urinary tract infections and may reduce inflammation in the intestines. Even if your dog isn’t having digestive or stomach problems, talk to your veterinary clinic Aurora, CO about adding a routine probiotic to your dog’s regular diet.
