We have a Westie - he's 6 years old and I can honestly say that both my husband and I feel he is the best of any dog breed either of us have ever owned.
As I type, I'm sitting on the couch with my laptop in my lap. Gizmo is "wedgied" into the space between me & the arm of the sofa. This is his usual spot. If we are sitting, he's cuddled up to one of us. At night, he sleeps on our bed at our feet, or cuddled up behind the crook of our knees (dh & I are both side sleepers).
He does bark, but I wouldn't consider him yappy AT ALL. He barks when the doorbell rings, when another animal crosses "his" yard, and at certain things on tv. Anything with a ball, particularly - we think he thinks they have his toy! lol
We have him cut about every 6 weeks. We'll also occasionally send him in just for a bath, but we also bath him at home too. He's very cooperative.
He is playful, but not rowdy. When he plays, he wants to engage your attention & boy does he have cute little tricks to do so.
During his puppy year, he did dig & chew. The digging was pretty bad if we left him outside in his little enclosure for any length of time. We have red clay soil here - white dog + red mud = NOT GOOD, lol. The only thing he really chewed on that was inappropriate were my dd's flip flops. She had to learn not to leave them out where he would get them. He outgrew it though, along with the digging, at about 12-13 months.
We have already decided that any future doggy addtions to the family will be Westies.
