I've hunted with a few good Partin dogs, they have a very distinct look to them usually... round muscled head, big doe eyes. Not seen one I'd want to bring into my breeding program yet, but wouldn't doubt if way back my dogs have some old Partin blood in them... do see that "look" show up on the head of some individuals occasionally...
Mark Chesser's got a good Partin dog he hunts.
There's a big ranch down in Myakka that has some dogs I'd kill to get some blood off of, basically RCD's, but that's how a lot of the cowboys hunt down there... One dog in particular looks like a cross between a BMC and a Dogo... a creme colored dog with a box head to die for lol.. probably a good 100# dog used on cattle and hogs... what makes me bring it up is, again, the complete originality of "type" in this specimen... just don't see dogs around that you could compare him to... a distinct line of cur for sure...
Def looks like some hound in the woodpile

Gees, anyway u could post a picture of the creme colored dog, how tall is that rascal?? Sure sounds like u discovered a sleeper strain, its driven me crazy trying to figure out how these curs got bred in the first place, one thing i found in fooling with the rat terriers is that almost every rat terrier can be traced to who was breeding that particlular type of terrier, u see it over and over especuially if you heavy inbreed like i do, thats why one should stay away from dogs whose history is unknow or a secretlol Might not mean anything if the particular dog is firecracker but start breeding one like that not knowing and you might get a missfire for sure. What do you know about the dogs you have now, are they all florida curs or what do yall call them and how are they bred?? Are they more a ruff type dog or a bay type dog or both??
