By far the worst.

All the pig hunting dogs are maniacs.
I speak from personal experience. For example:

Worse than that, catahoula mad-escape-artist skills are synergistic with the husky-mad-escape artist skills. One basket of mad catahoula escape artist skills plus one basket of mad husky escape escape artist skills equals four baskets total of doggy escape artist skills.
1 + 1 = 4
Our catahoula and husky are best friends and partners in crime. Our backyard fencing and walls look too much like the fencing and walls around human prisons.
My wife always has a soft spot in her heart for the difficult, less adoptable, animal shelter dogs. Pig dogs, huskies, dingos... Maybe I'm a difficult dog too.
The only truly good dog we've ever adopted, the only dog I've ever trusted off leash in any environment other than wilderness, was brought home by one of our kids.
