@Bowhunter57 Im sorry for your loss. That is a beautiful headstone and grave. Its clear you loved your puppy like she deserved.
We just put down our 10 year old GSD last month. One week she was fine, the next she was lethargic, didn't want to eat, and drinking way too much. She improved after a trip to the vet, but two weeks later, was back in bad shape. This time with a bloated belly. Took her into medvet. She was bleeding inside, likely from a ruptured tumor we never knew was there. We put her to sleep while she stood guard over us one last time. Just before she put her head down to sleep she looked at each of us and licked us one last time. That was probably the hardest thing Ive had to do.
We swore up and down we wouldn't get another dog. But we will. Just not now. The unexpectedly hard part was having someone ring the doorbell and there being silence.
