Same here. We've always rescued pups, but the last one, probably the most troublesome was an adult, she was older than we wanted, scraggily, quite ugly looking, but as soon as we walked in she was jumping and trying to get her paws through the cage, then was trying to cling on to us. there's only a few times I've managed to visit a rescue centre and not rehome a dog. She's a great dog now, still not the prettiest of things, still needy. But its a great feeling to see her running out on the hill, or lay sleeping at the end of a long day out. I do like having pups and watching them develop, but I'd like to keep taking in the odd adult dogs too, because their chance of being picked up is so low. She's so loyal now, it's like she knows we took her in and is lucky to be here, whilst the one we had from a pup thinks we're lucky to have her..even the dog psych reckons she has 'high expectations of life and gets annoyed if they aren't fulfilled'..
