Awwwwwww. He's gorgeous! Why do people feel they can smack Dobies around?
My second job as a vet was in a small animal practice. One of the vets there also worked at the city animal shelter. She and her husband adopted a big red/brown Dobie who had been abandoned after someone had broken his leg (it was likely a drug house). He was not too trusting either, but eventually got better. He was never good around kids and they never let him be around any.
Anyway, Paul is gorgeous! I know he'll get very pampered with you.
