Oh, she bites :(

I had to do something this afternoon that I never had to do before.  I had to turn down a dog due to aggression.  The owner adopted this beautiful (60+ lb) Shepherd mix a month ago from the SPCA.  Since then, her new fur kid has been extremely protective of her and the apartment.  She did warn me about this ahead of time, so we decided to start the meet and greet outside and go for a walk.  She took treats, let me walk her, let me pet her, did her business, and seemed pretty relaxed.  We then went up to her apartment where she snapped at me once, and then again when I tried to touch her toy.  The second time was a bit worse.  I had to be honest and tell her that I was extremely apprehensive about walking the dog on my own, and of course she understood.  We discussed training, behavior issues, options, etc.  It's tough because I really like them, but can't put my limbs at risk.  The owner understands of course, but it is just a crappy situation for all parties to be in.  The dog has aggression issues, the owner can't have people in her apartment, and the potential walker is scared of the dog. I don't claim to be a behaviorist by any means, although I have learned some things along the way.  I hope that everything works out for the best....
