Oh I am sorry to hear about Dixie! The loss of a pet is a heartbreak.

Hm my favourite pet would be..... A tank of fishies with a mini octopus in it. And I would love to have this just because it would look awesome at night, illuminated, with colorful fishies swimming around. It would just relax me.

If I would be an animal.... I would pick tardigrades because... Look at wiki

Tardigrades are among the most resilient animals known, with individual species able to survive extreme conditions—such as exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and starvation—that would quickly kill most other known forms of life. Tardigrades have survived exposure to outer space.
