You have some pretty feisty coyotes, then. The javelinas are all over Texas, coyotes or not.
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.
The coydogs run in large packs. They take down full size deer here right 50 yards from my front porch. One winter night they ran `round and ``round the house. I counted 18 going by in the moonlight. There are also large wolves here, bigger than a German Shepherd, but these mostly are loners.
None of the hunters here I know has ever even seen a porker anywhere. Just could be they are eating apples. The local apple orchards here 3 miles and 12 miles away don`t have any porkers around coz there are cougars in the area all the time at night going after deer that feed in the cornfields. My house is 60 miles from Peru.
