Dog Fashion clothes


I am 16 and this summer looking into getting a job / gig. The problem is that I am an active person, love to be outdoors / doing more physical stuff (I practically live at the barn, but I can’t do work there because of my feet problem). I have a problem with my feet that makes it hurt to walk and I am getting surgery soon so I can walk a little bit but not very much and it hurts to stand up too long.
Some things about me:
I love art
Love animals (horses, dogs, cats, etc)
ok with kids but can’t spend too much time w/ them without going crazy
cant stand sitting in a building all day, though i guess i would at last resort
don’t really like clothing / fashion

what are some good / unique / interesting job ideas? I was thinking of selling art but I am supposed to keep my art for my AP portfolio so that might be out.
ALSO is it too late to get a job since its already summer? I know a lot of people my age are looking for a job and many cant find one…
thanks
PS I dont have any real experience or resumes or anything, and I DONT want any kind of internet thing because its probably a scam, i want REAL work for both money and experience.
