I have two beagles , ones a mix, they are 12 years old in good shape. They sleep a lot but they can jump up on the bed and they both are very mobile and healthy. Had to have some growths removed recently. But they seem no worse for it. Good dogs, I love them a lot. I don't know how they will be when one goes.. I will not let them deteriorate or suffer. They have been too good. When it's time I will put them down. Question I have is should I get a young pup now? I think they have another two or three years left. Would love to hear people's thoughts.
