About two months ago I had to put down Mufasa. He was one of two GSDs that I have. I rescued him from a dog shelter many years ago and I considered him my son. He reached the respectful age of 14! My boy's legs gave out and I had to make that painful decision we all make from time to time. My other GSD, Sid, just hasn't been the same since. For the first three days, he actually wouldn't eat and barely drank water. I consoled him the best I could and it just broke my heart! He's better now but the spark never really came all the way back in his eyes. I have been looking for a new friend for Sid but haven't been too successful yet. In the mean time, what can I do to help him feel better. We already go for walks at the park, he goes everywhere with me. He knows he will get a burger at the drive thru and that perks him up. But there must be more I can do. Any suggestions?
