I know some that have used them successfully. I have a squirrel/**** dog Mt Cur and I think he would be a little too gritty for hogs - he would want to get in there and fight them. I am sure it depends on the individual dog and how they Have been brought up. Mine has been encouraged to kill a **** or possum.
Depending on what u want, I may have a red leopard male and a blue leopard female from my last litter...been thinking abt giving catahoula breeding a break for a while until I can spend more quality time with my dogs...contact me if interested (501)941-8587
