Odie is my lab/beagle mix. He is 15-years-old and is showing signs that he may be near the end. I'm having a hard time getting him to eat and he is losing weight. He refuses his regular dog food, will take a couple of bites of canned food. The only thing I found he will really eat is cooked hamburger. Any suggestions of other foods I can try? Also, he seems obsessed with going outside. Once out, he just stands there. Lately he has been laying down in the snow and going to sleep, something he never did before. As soon as we bring him in, he begs to go out again. I wonder if his mind may be going. Any one else had an experience like this with an old timer? I sure am going to miss him when he goes. He's a great dog.
