When a dog has a Urinary Tract Infection it's always best to seek a vets treatment as that really is the best course of action.
However not everyone can afford a Vet visit and a good way of treating your dogs Urinary Tract Infection at home is to use Apple Cider Vinegar in the dogs water bowl along with the dogs water.
For smaller dogs add 1 teaspoon of Apple Cider Vinegar to the water and for larger dogs add 2 Tablespoons of Apple Cider Vinegar to the dogs water.
The Apple Cider Vinegar is antibacterial and will kill off the bacteria causing urinary tract infections.
Cranberry Juice is another good Urinary Tract Infection Treatment for dogs and even Humans.
To prevent future Urinary Tract Infections make sure your dog has plenty of clean drinking water and urinates often and keep your pet as clean as possible especially in the private areas.
