Hi Ana, I'm so sad to hear about Merlin. You would think that when our furry friends reach that stage it would make the decision easier, but it doesn't soften the pain of losing not only our pet, but a beloved family member. Just know that when the time comes you are giving Merlin the greatest gift of all by letting him go to rainbow bridge to be the dog he once was. I am sorry you have to go though this. ________________________________ Michele
