King Levy is a bearded dragon
Tell about in a minute. First, who wants to hold him?
Make sure his feet are on something - arm, shirt, shoulder. Make him feel safe and squirm less.
Do not pull tail, it’ll fall off. Why?
Do not pick at his shedding. Why do they shed?
Keep hands away from his face. Why? Levy never bit, but can. He does lick. Getting to know you. But shouldn’t be close enough.
Don’t kiss him or rub face on him. Wipe hands after with baby wipe. Germs can hurt humans. He prolly doesn’t, but all reptiles can.
If you don’t want to hold him, don’t have to, just tell Ely. She’s going to help.
Bearded dragons
Levy eight months old, but can live to 12 and can get 3 feet long
