I’ve taken dogs and cats to a vet to be put down when it was their time. It’s always hard on me, but I think it’s the right way to handle it because it’s always been a peaceful exit for the animal. Vet gives them the shot and moments later they close their eyes like they’ve fallen to sleep. I’ve always been there petting them in position for them to see me so I can comfort them to their end.
I learned many pets ago that this hard time at the end of their life is absolutely worth all the years of smiles, laughs, friendship, companionship and love they offered me for their whole life.
The hardest one on me was my favorite. “Camas”, my female yellow lab was a joy to live with. A real “easy keeper”. Never did anything wrong her whole life. I said many times I should have named her “Happy”, because she always was. Best years of my life were the ones I spent with her.
OP, you and your lab are in my prayers today.
