You are in Florida… a sad hotbed of byb/puppymill country. Yep agree with the rest, looks basenji to me too. You might contact Pam Hamilton because she'll know if you are in the hoarder area. I'll ask her to check in here.
Look at the BRAT mixes:

Check out Tia. I think that's what you are looking for. :)
Then look at Tyson and Shiloh. Not the right coloring, but similar build and coat….
