Oh, wow! Yeah, we have a big obnoxious lab that we got for a family Christmas gift and he really pushes our buttons! First of all, we are most definitely "cat people" and have our 2 little old ladies (11 & 10 year old cats). So, we (I) thought it would be great if we got a big dog who could "grow up" with our daughter and hopefully ward off any unwanted visitors.
Well, this guy is smart and very eager to learn, but he's also very, very pushy! He shoves around his 65lbs and knocks my daughter over, trips me and DH, and torments the cats. We can't complain, too much, though, because he has zero aggression towards us (or the cats, or other dogs) and is very protective of our yard! We just got a companion dog for him (a chihuahua/terrier mix) and it's hilarious when the 4 of them (cats & dogs) get all riled up!
The big cat (she's about 12lbs) gets mad at the big dog (65lbs) for standing too close to her; he irritates the little dog (he's about 8 lbs) by constantly sniffing his rear and stepping on him; and the little dog is infatuated with the little cat (she's about 6lbs) and stalks her all around the house! The little cat just wants to find a warm and quiet hiding spot where everybody will just leave her alone! Sometimes, we just sit around cracking up at the "dynamics" of our zoo!
