We have a wonderful (but previously abused) rescue dog who is great is virtually every way except for ONE major issue: boarding.
He gets very scared of new people and becomes aggressive/reactive. This is NOT an issue when we are around..... he can be around anyone, walk anywhere, etc... we can have people in our house no problem - he'll just ignore them. Truly the ONLY issue is boarding...
I'm aware of some "no/limited contact" boarders but not in Greater Houston. Some vets do this. Basically you walk your dog to the dog run (cage) and the dog doesn't leave the run while you are gone. They can separate it into two for cleaning and food delivery. This way people don't have to directly handle your dog. We don't want him in this kind of space for a long period, but perhaps a long weekend.
The goal is random handlers don't have to handle him and we don't have to worry about anyone getting bit. (He's never bit anyone but we're worried he would bite if he got too upset).
Any suggestions are appreciated! Please note: NOT seeking a trainer at this time (we've already been told by a high end trainer that we have the best version of him we're going to get) and we're not interested in punishment-based training - he has already been abused by the previous owner. We also don't want a Rover or similar person handling him...
