I have a 2 year old RT.  She is very loving and playing with my daughter and I but she doesn't like anyone else.  We have tried treats to reward her with good behavior and about anything else I can think of.  If someone else tries to pet her she shakes and will even try to bite them and a couple of times she has bitten someone.  My vet has put her on meds which helps somewhat and she have been spayed, which I hoped would help.  The problem is in a month and half we are going on vactions and she can't come with us.  I have to board her because no one will watch her for me, but I'm afraid she is going to feak out at while there and try to bite or will bit someone.  I'm at a loss of what to do.  Any ideas or suggestions?

We are leaving her for 5 days.  I thought of taking her to my vets, but when I take her into the vets office she has to be muzzled because she bite someone there when I took her in to be spayed.  I told them of her dislike of strangers and on the good side she did let someone hold her but because she doesn't like strangers and we were afraid that she might bite they muzzled her.  Well she got free from her muzzle and bite one of the vet techs.
