I am glad he is doing better! I have 5 dogs and they all sleep in their own houses at night. Lately, my 8 month old biewer has decided 4 am is a great time to start barking. Honestly, I think the cats are going in and waking her up so I will get up, and they can try to steal my spot on the bed. The cats know they will get in trouble for sleeping in my spot, but I am sure they hear me comming back to bed and jump down looking all innocent. Perhaps I am being paranoid, but I am sure waking the puppy up is an evil cat plot and part of the cats plan to dominate the world.....Either that or the dog has got to go potty....I vote for evil cat plot!!
