LOVE THE NAME!!! hehehe
1. he will have cotton coat...just like Carmel! It will be hard when he gets matted so make sure you brush it often. Otherwise, it becomes a disaster!
2. Yeah, he will definitely be over 4 lbs. I think you should look up the growth chart. Carmel was not even 2 lbs at 10 weeks of age and he's now 6 lbs full grown!! You never know though! Emma was 2.5 lbs at 12 weeks and she's around 4 lbs now.
3. I think his ear will be down...Carmel's is sometimes down (the hair is heavy). Right now, it's at one up and one down. haha Either way, I don't care, I love him too much to care!
Also, your baby is a CUTIE!! I love his tail! I also like his tag a lot!! Super cute!! It fits him perfectly!
