I have a 12 year old boxer that is Peeing uncontrollably and won't stop drinking water. He is running to the door to go outside but before I can open the door he starts peeing in the house. I have to take the water away from him. He doesn't seem to be in pain. Can anyone give me advice? I know I have to take him to the Vet. , just wanted to see if anyone has any ideas what’s going on with my dog. He is an incredible dog. Won't be the same without him!!!!
