...alright, just gonna ignore that whole can of worms...
Honestly, the best animal is something that fits... you, personally. When I was dealing with my depression, I had a dog since I'm a very physical person and running around/playing with The Bastard (actual dog name, thanks dad) was really good for me. A friend of mine is a very analytical person who likes to order things around her, so she ended up taking care of a bunch of Tarantulas for her therapy. Another friend adopted a couple of Rats, since they're pretty low-maintenance while also giving you a lot of physical contact for sad moments. I've also heard good things about cats (though they're honestly the same maintenance level of dogs), since they're pretty smart and can often comfort you by their own volition (if you take care of 'em well, that is). Lizards and turtles are also good, since they're fairly low maintenance and take up little room, so you don't have to stress too much with 'em.
If you do want a dog you can look into Therapy dogs and anything related to getting one without it costing you an arm and a leg? I know they're a thing in Australia and I've heard about 'em in America, but don't really know all the finer details.
...but yeah, it's just really what fits you best. Do you need a pet that's low maintenance? High maintenance? low energy? High energy? Something that you can cuddle, something that will comfort you itself? Something you don't want to touch with a 50 foot pole? It's like regular pet shopping really, just taking into consideration the nature of your depression as well.
