We have always have had labs in the FTJ house, even when I was a kid -- and some of them are just born to have bad hips and joints. My dad's dog is going through a lot of the same things your dog is, and is probably about the same age -- My dad's dog messes in the house all the time, and has a hard time getting around -- probably should be put down, but my guess is my dad is waiting until he is at peace with the whole thing. One thing I learned about labs, is that you have to keep the weight off of them, and not feed them table scraps -- we have a lab right now, and she is very skinny and healthy -- my dad's dog put on some weight, and that is now a big problem for her. We had a scare with our dog -- looking like it would die everytime it walked -- turned out to be Lyme's disease and was easily treated.
