@Joe C, MrMagic: Best of luck with the dogs. When I was a teenager, I had one of these. https://www.niabizoo.com/animals-habitats-details/mexican-red-legged-tarantula/ Her name was Morticia, and she was quite friendly. She would walk up your arm, across your head, and down the other arm. She'd patiently wait till you put your hands together, and she'd do the circuit again. When we moved, I donated her to a pet shop in the hopes that they'd find her a new owner.
