juno has changed leaps in jumps over the years not just in design but your art style has also dramatically changed, I forget what breed he is but if he is related to canines I think his muzzle is a little too blunt for that.

As for hair, it depends on the time and setting, from there it could be easier to look at photos from that time and catch some examples of what real life people used.

Nope Juno is still a ferret, there are no canid chars in the story aside from a spirit
as for hair he used to have longer, not long, hair but seeing as hes a military character I wanted his hair shorter. I like this style on him but I think I went about it the wrong way
