My wonderful lab was PTS a few weeks back. We were there with him when he went into his forever sleep. It was a horrible day and the pain of this memory will never go away.
Our vet was lovely throughout the process. It was clear they are real animal lovers and they shared our pain. I was so impressed with the way they interacted with us and our very poorly dog.
They even sent us a very touching handwritten card the following week... A very sweet touch. It must be very difficult for them.
