What tests did your vet do? It not common for a dog that has free access to the outside to decide to pee inside after being totally trained for that long. I would ask for further testing on his kidneys and bladder.
The only other thing I can suggest is to check for something new in your kitchen that could be attracting him to pee there like a small area rug. Many of those small rugs for kitchen and bathrooms have a rubber like backing that have a scent that will attract both dogs and cats to potty on them. I kind of doubt that is the case here but it is something to consider since he seems to be attracted to just one area according to your post. |
