Since we brought Ryder home with us only last month only weighing 8 grams and measuring at 6.5" he has grown and filled out so much already! As of today he is now 25 grams and 8.5" long. I hate that I don't know exactly how old he is but I'm guessing 3 months old ??? I know that measurements and weights vary with each dragon but does that sound about right?? How much do they gain with in a week normally?
