Hi MaddyDog! I'm happy to hear that your dog has responded so well to this camp! I've got a friend who has a dog of 3,4 or 5 mixes, is 4 yrs. old, stands a bit taller than a b but he weighs 40 lbs. or so. His is like your dog was but, he's not just aggressive to other dogs, it's people too! When dogs growl, Ruff attacks & with people, he's not always a biter. About 4 months ago, I was at his house when Ruff got out of the kitchen & came straight for me! He wasn't able to catch him & I put my hand out so Ruff bit my hand, leaving 2 fair size holes in my palm & a couple of small poke holes in the top. He was chewing Ruff out the entire way back to the kitchen (was raining out so I told him not to put him outdoors). He kept saying he was sorry over & over but I told him to hush up! Just pour some peroxide over my hand & give me a couple sterile gauze pads. He started talking about putting Ruff down & I told him "Don't do that!" Ruff came from a shelter too but he was funny as a 1 & half yr. old, snarling at everything, even at his toys! I was wondering if you'd give me the name of the vet/trainer you used (cost too) so my friend won't put Ruff down. I think much of it is our fault for not doing some training soon after he got him plus, we'd laugh at him when he was being gruffy! I've been bitten by several dogs before Ruff but I don't want him to put him down as he's his Companion Animal. He's had all his shots & I'm up to date on my tetanus. You can post it in a private Chat Message on here if you would. Basicly, Ruff is a good dog & he shouldn't have to give up his life because we didn't get training for him! Please, send me a Chat with the info so Ruff doesn't have to die! Thanks, Nancy
