Hello again everyone,
My fiance and I adopted an ex-racing greyhound about 4-5 months ago and he was great at first. About two weeks later he started peeing all over the house marking his territory. He marks everything including dishwasher, leather sofa, kitchen chair, and the recliners. We clean absolutely everything with the Petzyne so that even he can't smell it. This seemed to work for roughly a month, but now he's back at it again. My fiance and I are going crazy to the point where I joke about peeing on his head one day in the hopes that it will stop his marking. If anyone can offer any advice that would be great.

Thanks everyone
