This breed is a den animal making it the perfect student for crate training. The crate will provide it with a small space of its own. Leaving the dog on its own when the owners have to be out for the day would not be a problem. However, the Welsh Terrier likes to dig holes and have been known to climb or jump fences.
Yorkies are easy to train, although they can sometimes be stubborn if owners do not give the dog proper boundaries. They can be difficult to housebreak. The Yorkie is an excellent watchdog. When owners display pack leadership to the Yorkshire Terrier, it is very sweet and loving and can be trusted with children. The problems only arise when owners, because of the dogâs cute little size, allow it to take over the house.
