If your dog is peeing blood, it’s important to take them to the vet as soon as possible. Many of the conditions causing this issue are treatable, especially if they are diagnosed early, and delaying treatment can cause complications. Before your appointment, you can help your pup at home by offering them plenty of fresh water and letting them out regularly to toilet. You should also keep a close eye on them and update your vet if there are any changes. Do not attempt to give your dog cranberry juice or any human remedies for UTIs or bladder problems as these are unlikely to be beneficial and are not extensively tested for safety in dogs.
