I would say that he is cross between a beagle and a bluetick, his markings are blue tick and the down size would come from the beagle.

I had the same problem as you with my dog Hannah, when I first got her everyone said oh my you got a blue tick, thats going to be a big dog. I didn't know what breed she was all I knew was that her mom was a pure bred beagle. As she grew up the vet told me that she either had some GSP in her or was just a plain ol beagle with blue tick coloring, which are not that commen but it does happen (a show breeders nightmare).

He sure is handsome he has the same markings as Hannah does on his legs and chest.

she has brown freckles up her legs and it changes to black freckles on her chest and belly.
