We have a 2.5 year old toy poodle/shitzu. He is well behaved and very affectionate. We adopted him 6 months ago, he has been to the vet, had all his needles, was neutered. Our only problem, he pees on the living room carpet approx every month. We have cleaned the carpet after each time he piddles. Today, we removed the area rug in question, washed the hardwood floor and waxed it and went out to dinner. When we came home, there was pee in the same spot as the carpet. He was taken out to pee before we left for dinner.How can we change his behaviour Thanks for any help you can offer. Tom Tomkins
