Hi there, welcome!
Your baby is a real cutie pie!
I'm currently waiting for a black and tan smooth female Chi as a sister for Lexi, I can't wait I just love them.
(I was meant to be getting two older females as some may remember, but that fell through last minute unfortunately. But I'm happy because they got to stay with their owner after all, re-homing can be so stressful for dogs.)
Lexi came to me at 7 weeks old, and although they shouldn't be away from their mum at this tender age, as long as you keep a close eye on Rocky he'll be ok. Just watch for hypoglycemia attacks, make sure he's fed 3 meals a day to keep his sugar levels up and just take extra care with him
