This is the New Addition to the Family, Arlo. Anyone Have Suggestions on the Crossbreed?

I recently snagged this handsome boy from a no kill shelter. The vet said Catahoula and something, which I agree with. That white belly stripe and front leg socks have me stumped though. I’m gonna get him DNA tested eventually but he’s already made a trip to the ER for an eye ulcer, which put a dent in the budget this month. Any thoughts on the Catahoula cross or different cross altogether?
