I had a doberman, It's been 4 years now since he passed away, but it feels like yesterday. I'm not planning to have a pet at the moment since I want to be pretty mobile, but in the future when I settle down I'll get another dog, most likely doberman.
My choice of pet seems weird now you guys have all posted. I am a keen reptile hobbyist, I have a large number of snakes (mainly pit vipers and pythons) and lizards (mainly geckoes and varanids.) I also help fund and maintain a private research facility that keeps Marmosets and Tamarins as well as many more reptiles. My biggest pet is a 9' long New Guinea Crocodile Monitor (Varanus salvadorii for all you taxonomy buffs)
