Since this is my first winter with Izzy, Im not sure. It could be the cold. I want to sleep more myself. I think as long as he's eating and plays in between naps, he should be fine.
The breeder named him Sleepy...so if he sleeps alot, its normal to me. Hes kind of a bum

He will lay around all day if I let him....just look at my avatar. Right now he's asleep in my lap...what a lazy lima bean!
