Okay, so maybe your Welsh Terrier isn't the best behaved dog in the world. Perhaps he likes to pick and choose when to behave to always keep you on your toes! Our funny Welsh Terrier t-shirts and other products are sure to get a chuckle. The text reads, "My Welsh Terrier is extremely obedient" - but the word obedient is crossed out, and naughty is scribbled in below. The design is covered with muddy paw prints and splatters as though the dog has jumped all over it.
