Thunder, my beautiful, rambunctious, 13 year old labrador, is failing. I fear it's his age, but his spunk is still there. His body, keeps deteriorating. He has no look in his eyes that says "it's almost over", he still has the look from when I brought him to my house 13 years ago. We've been trying to get weight on him, but he's not eating as much. We had to switch back to his "normal" feed as the raw feeding, cooked feeding, Eukanuba and Diamond all made him throw up and have his pancreatitis attacks. The vet says it's just something to expect with elderly dogs...their bodies will go down before they will. I just can't give up. If he's not willing to, I'm not willing to. Today, he was running, rolling and jumping in the snow. Truth is, he shouldn't have even been able to walk. He looks like a skeleton. Is there ANYTHING I can do to get his appetite back up? He's a walking skeleton...but is still so lively. He used to be 84 lbs. and looks like he's down to 60 something. His pancreatitis just makes everything come back up. He pooped while I was there today and it did not look good. It was like projectile diarrhea. It was brown and was VERY mucousy. There was hardly any chunkage at all in it, if any at all. He is housed indoors for the winter. It's simply too cold for his hips to endure being outside except to use the bathroom and to play. Something like this, but in the snow: "Yes, I AM king."
