I’ve heard javelinas can be pretty fiesty. Here in Florida the coyotes don’t much bother the wild hogs. The panthers will take them at will but not much else does.
Our contractor, in Arizona, said that dogs get ripped up by Javelina. I suspect that panthers can hang on their backs while they go after the neck.
We just bought a house on “Javelina Road”. During the escrow period while we could still back out we were standing in the back yard with the Realtor when two javelina came around the side of the house and wandered into the forest behind the house. I told the Realtor that if this house had been on “Grizzly Road” the deal was OFF!
