Clipper is still hanging in there, my big old sweet wild heart. The lump on his right side was the size of the palm of my hand 3 weeks ago, it is now the size of my hand. He still does not have pain when I lay my hand on it, but has difficulty getting up because it is "in the way". His breathing still seems ok. I have upped his tramadol to 3 a day. He still eats and wants to go outside, sometimes will pick up a toy for me to toss. He did have 2 times he pooped while laying down, once in the middle of the nite, I heard it and got up and cleaned it up and him, I think maybe he was asleep. Then he was laying in the living room and his tail started twitching and some came out but got him outside. He seems happy still, and is eating only cooked meats and canned dog food. Still likes his milk bones but won't eat dry dog food any longer. He still takes all his supplements. It is hard seeing him become weaker. But he still has spark to his eyes and seems content. Whether it is osteosarcoma or chondesarcoma they wouldn't know unless they had the tumor, but he is 12, I wouldn't put him thru that.
