How old is he/she? I have a almost 8 week old pup here, and got her when she was 6 weeks. She slept ALOT just as u said for the first week and a half, and still does sleep 2-3 hours at a time, and then wakes up to eat/potty and sometimes plays and just goes right back to sleep! Nothing to worry about though! Puppies sleep all the time. If she/he is an OLDER chi, such as....enior or maybe just the chi's first year, I wouldnt be too sure, and maybe one of the other members can help you with that :wave:
