I've got this big Dane/lab mix, about seven years old. We'd had several danes and rescued this boy thinking that the lab part of his gene pool would contribute to a little bit longer life span and less chance of the cancers that danes seem to be plagued with. Well, like I said he's seven now, weighing in at about 180 and his hips are going. He's afraid to walk on the wood floor anymore because he falls and hurts himself. He also has some growing lumps on his shoulders which I fear are the lymphatic cancer our last big dane died from. I just hate to see him so afraid of getting hurt and then of course when he falls he does get hurt. Is there anything I can do for him or is this the time we start thinking about putting him down before he gets bad. This is Boo when he was about six months old.
