I also have a 5 month old yorkie, male.. and he was previously very well trained which surprised me..last two weeks, started peeing in house, on floor, on occasion... more everyday... lifting leg , and squatting, called vet she said to neuter right away, as this is a dominant male activity.. and he can hold it over night for like 9 hours no prob.. soo... looks like he is due for a vet visit
