After years of research, scientists have found that certain compounds in cranberries can prevent  urinary tract infections in humans. The compounds don’t actually kill the bacteria, it would take an antibiotic to do that but the cranberry compounds can act as a preventative. Amy Howell who is an associate research scientist at Rutgers University says that the disease causing bacteria cannot stick to the bladder wall and lose their ability to multiply. The bacteria is then washed out of your system. She says that the same process works in dogs. Not all cranberry products are equal. Ask your veterinarian for cranberry products that have hard hitting bio active properties. So hold off on the pet medication until you try a cranberry product for your dog’s urinary tract.
