... If you don't want to put the work into finding the right home, or if you are forced to take her to the shelter in the end, take her to your vet instead and put her down. Might not be the most popular opinion here, but I work at a shelter. I've seen the sad faces of dogs who just cannot forget their past lives, and cannot seem to open themselves to a new one. Its better that the dog goes quietly in the arms she knows and loves, then in a crowded shelter, scared and alone, or winding up in the hands of someone who can only mean trouble for the breed.
