There are pros and cons to adding cider vinegar to a dog’s drinking water, with the recommended dose usually 1 teaspoon to 1 tablespoon per 50 pounds of body weight. “People often talk about adding ACV to water bowls,” says canine health researcher Mary Straus. “My feeling is that if so, you should also offer plain water, just in case your dogs don’t want to drink the water with the ACV in it. You wouldn’t want to risk their drinking less water and possibly becoming dehydrated.”
Is a daily dose of apple cider vinegar good for your dog? Unless your dog is allergic to apples, he or she isn’t likely to suffer a serious reaction, and within a month you should be able to tell whether the addition is helping. Commonly reported benefits include improvements in skin and coat condition, a reduction of itching and scratching, the elimination of tear stains on the face, fewer brown or yellow urine spots in lawns, increased mobility in older dogs, reduced flea populations, and an improvement in overall health.
