Hi all, I was wondering if there is a way to calculate how much my puppies will weigh when full grown, My pomchi is 4 pounds at 7 months old, and my Blue Chihuahua is 4 pounds at 8 months old, and my other chi is 3 1/2 pounds at 4 months. Is there a way to tell how big they will be when full grown? And at what age are they usually full grown? Thanks alot. :?: :wave:
