Catahoulas will work great for tracking wounded deer!! I raise the and use them for Hog hunting and all around farm and and guard dog.
One piece of advise...get a young pup and train him obedience at a early age. CLC's are a very domineering and headstrong breed and must be taught the basics at a early age. Do this and you will have no problems.
I have owned about every breed out there and there isnt a more loyal, smarter, and better all around dog thn a Catahoula.
