Take your dog to the vet. My mothers dog could not pee and he had a blockage and had to have surgery.
My Dog Is Having Trouble Peeing, What Should I Do? Is There A Home Remedy?
Bible's right. No home remedy's for infection or blockage. Waiting generally causes the problem to become worse, possibly resulting in death, and it's usually VERY painful, just like when we have urinary tract problems. The sooner the better and hope your pup is feeling better very soon.
