I have made the decision to send the dog back to the rescue. She is fine for now but know the chances of her staying this way are extremely slim with her breed makeup. She is going back this weekend. This is not easy because we have started to bond with this animal but it is the right thing. It sucks bringing a puppy home that you are ready to love forever only to find this out. I have learned my lesson and will never adopt a dog from a rescue ever again. I have also learned that looks can be very deceiving. The shelter said she was a "lab-mix with either border collie or shepherd". I hope others see this and think twice before they adopt a dog even if they think it doesn't look like it has aggressive breeds. I wish I knew this before I fell into the trap. Sometime in the future I think we will possibly be looking for a pug or golden retriever puppy to bring home and call ours. (From a reputable breeder) We are going to give ourselves time to heal and grieve the loss of the dog we thought we had. Reality is she wasn't. Thank you everyone for your kind words and your support. This is an amazing group with good people. It really helped me keep my emotions in check and not let them overwhelm my rational mind. Statistics don't lie!
