[Discussion] Tipping dog Boarder

I have to board my dogs for a couple on nights. One of them is a hound mix (51 pounds) and the other is a Yorkie. They are both rescues. The Hound mix is older and not very well behaved. He has gotten significantly better sense I have came into his life. Prior to that he was me wife's dog before she met me. He failed 3 obedience schools. She tried to return him to the rescue group but they stated he had been returned 3 times before and this was the 4th and would be put down. So she took him back (this was prior to meeting me, I wouldn't have returned him) The issue I am most concerned about is he lets to run out the door. He does not do this anymore at home, which was a major accomplishment for me. However, I feel he may try to escape the at the boarder. He also does not get along well with other big dogs. He has been there before a few times but not recently. I was wondering if you think tipping up front would help ensure his safety? I will also point out he can be difficult to deal with. The dog is my best friend and I worry a lot about this. via /r/dogs http://ift.tt/2sxiVFV
