If your dog or cat has blood in its urine or pain during urination or frequent urination, go to the vet immediately. If your pet gets bladder stones, it may require surgery. Some pets get this from their diet, others are susceptible by breed.
Always be sure your pet has access to water and frequent chances to urinate.
