yeah, 8 is extremely young for a cairn.....but he developed cataracts, and then soon after developed "doggie alzheimers"....it was horrible to witness. barney was sooooo energetic, and then all of a sudden, he wasn't......my mom cried all the time. she got used to him being blind b/c he was fine with that, but it was when he didn't know where he was, and then he had a seizure that was the kicker for her. the last thing that happened was he had vertebrae that were separating, so the only thing he could do was sit on his lil bed. when my mom picked him up to take him outside, he would scream
like a human and then isht himself.

finally, we just had to put him down........the vet said he had to have been a puppy mill dog b/c cairns never have all those problems. mom swore she'd never get another dog, but then here we are with oscar who's a crack head and will prob live to be a billion.
