Oh Beth! I am shortly behind you in this tough decision. I have a 13 year old boxer who is currently doing great. Though, he has seizures occasionally and I know that at some point, he will begin his decline. When I look at him, I see him through his whole life. He is my buddy and my best friend. He recently decided he had eaten enough dry kibbles during his life, and promptly stopped eating. I added wet food and he's back to gobbling down his feed. He has gained weight and is back to his spunky self. I can totally empathize with you. I think Oak gave you phenomenal advice. You may know *when*, you may not know. But you love your friend, and you have his best interest in your heart, so whenever you arrive at your decision, it will be the right one. We do the best we can for our animals while they are in our care, and that is the best we can do. Somehow, I think they know this. When I look into the eyes of my furry friends, I know they understand our intentions, and somehow that makes it better for me. I'll be thinking of you...
