I had a terrier mix who had separation anxiety so bad that he broke off all his teeth trying to get out of his crate. Now, that said, he was THE BEST!
I currently have 2 rescued dogs that are great. I was going to make a specific post about that sometime here soon as they are retired racing greyhounds and the group that I adopted from is about to have 50 more dogs to ship out soon.
beb - These dogs are low maintenance house dogs if you're interested and a heck of a lot cheaper than a bulldog.
