Maybe something happened and she had to move or leave. If you still have her apartment key and would like to return it, you should call and let her know you would like to get it back to her. You can always go by there and knock on her door or let the office know at the apartment complex and return it to them. Or, you can just let it go because sometimes when people up and move they change the locks anyways.

You might need to find a different Vet, you can also try adding more fiber to her diet or probiotics. Pumpkin, is good for fiber and alot of dogs like it. Try mixing some in with some canned food. She may just be constipated and need a little help, so not sure if it is actually the leash or not. Here's a web page you can check out to get a few ideas. I hope it helps as it's not good for her to go even a couple of days without a bowel movement. http://pets.webmd.com/dogs/dog-constipation-causes-treatment (http://pets.webmd.com/dogs/dog-consti...)

You should try ignoring him when he gives you unwanted behavior. If he is lunging at you, when he does turn to the side with your hands up away from him, but don't say anything. Every time he does the unwanted behavior turn to the side and ignore him. Also use male wraps to keep him clean.
