Breeding ?
I didn't see where Heather said she planed to breed - I read her post with the understanding she was looking for a weight and size guess ?
Heather - at 8 months - he does sound pretty little at 3.5 pounds - but 12 " sounds a little long for that weight - are you measureing correctly ? I have a hard time with my girls getting good measurements -
Do you have pictures of him ? I bet he's just adorable ....
