I have not had time to read all the other responses so sorry if I am redundant but the fact is you brought in to your environment a four year old dog, that as you said might have been abused, you cannot and should not expect her to blend right into a life exposed to other dogs. It might take a year maybe longer maybe less until your pup and your Mom's yorkie can be a happy little group. This is why some choose to get rescues and often others do not. I commend you for taking in a rescue but often that require more work and paticence because not only are you tying to teach good new habits you are trying to work on erasing the past pain, abuse, and fear. |
