My son has a 7 mos. old beardie who loves loves loves to jump. Well, he was on his lap outside on our very high deck, Spike (dragons name) jumped from his lap and ran as fast as he could and jumped off the deck. Now, our deck is about 8 feet high. He landed at the bottom on all fours on the grass. He appears to be fine, but I am concerned. If he is walking ok, should I not worry?
