Nanook is eating fine and acting normal....when he is awake. The past few days he has been sleeping TONS though, I mean tons. He has an apt on Wednesday for a check up but I was hoping to find out if this is normal maybe during a growth spurt, or maybe weather change...it has been getting warmer out. Just looking to set my mind at ease I guess. I think with the experience with having a healthy lab one day to him having cancer and gone with in weeks makes me over think things now, I worry.

Aw! That's so sad about your lab! I wouldn't worry too much about the sleeping more, I'm not sure if they sleep more during a growth spurt, but it makes sense. Just mention it to your vet during your appointment, but i'm sure he's fine. Especially if he's eating/drinking/peeing/pooping normally. The weather may have something to do with it. My cats turn into slugs during the hottest months of the years. Just when I start to think they are mellowing out and getting old, winter rolls around and they are back to their usual neurotic selves. I love his markings, by the way, it looks like he's about to run in for a touch down.
