ive seen some that were 1/2 1/4 1/8 and even 1/16th "foxhound"
seemed to have exceptional speed and endurance-
have seen some i really liked -
the fastest treehounds ive seen will run with the average foxhounds ive seen--
seen a few foxhounds that were great cold trailers-
the average foxhound ive seen has NO cold trail in them
--if you need more speed and dont care about keeping registered dogs i think its a great shortcut to get it- ive used some - liked them alot --
dont have any now--
you have to be ready to give up a little on tree power- maybe cold trailing too
have to be selective to get any cold trailing out of either breed
lot of pure foxhounds arent gritty --ive seen pictures of over a dozen baying a small bobcat--ive seen some scared to death of a coyote
i had one that would cold trail .run and bay or kill a big coyote--alone
he was areal good part time , bear dog-seen him tree bear , coon , fisher , bobcat --
i know he was at least 1/2 registered foxhound -im not so sure he wasnt a crossbreed --if i had known that he was going to be a tree dog id never had run him on coyote --

all the cross breeds ive had--i didnt know anything about the foxhound side of them-- some were triggs julys running walkers- my buddy had a great english foxhound that looked and treed like a treeing walker--was a super cold trailer - gritty- -bug eyed bay dog --
he has several and thats only one ive seen --
anyways what im trying to say is-----choose both sides you breed very carefully--wont be great just because they are crossbred-but ill bet they will be faster track dogs than the tree hounds you cross with -
need to find some grit ,cold trail , some treeing or at least hard baydogs, from the foxhound side- all foxhounds dont have it-- a fox weighs 10 lbs - and is no fighter --
i went thru quite a few foxhounds before i found any with enuff grit for bear or even coyote -
i dont even like to say foxhounds--i lump them all together "coyote dogs " -- lol
the speed and endurance is almost automatically going to be good
