I am insanely jealous. Looks like you got the whole world on a string, buddy. Good for you for recognizing it, too!
It is obvious both of those hounds are purebred dogs. I do not see any cat, coon, possum, carp, deer, or other blood in them....yup, pure dog. Little of this dog, little of that dog, but all dog! Best kind ever! My old mixed breed (mostly sheltie, my guess) was an excellent squirrel dog. She'd tree all day long and follow that squirrel around the trunk no matter what they did. Pity they were only little chickaree squirrels (Tamiasciurus hudsonicus) that weigh only a wet fart heavier than a chipmunk! Still, I'd treat her to a couple days every fall of nothing but treeing squirrels and getting treats for doing it!
