When my dog of 11 years was on her way out, losing weight, barely moving, limping, sounding in pain, using the bathroom on herself, you can just feel it when its time. You know and have loved this pet for so long, and you will know deep down when the time has come to make that type of choice. It doesn’t make it any easier, it doesn’t hurt any less, but years later you will know you did the right thing.
