Replacement,

Collared Peccary and Javalina are the same animal. We have them in AZ. They are neither as smart or as hard to hunt as pigs. Eye sight is poor and they don't seem to hear very well either. But they do have great sense of smell. Menace to dogs which they figure are coyotes and are proficient at killing. I have had one encounter on a friends Golden Retriever which turned out pretty nasty. Killed two with 12ga birdshot at very close range to get them off the dog. Dog was within minutes of bleeding out when we got her to the vet, but she survived thanks in part to being an overweight golden with lots of fat and hair around the neck. Javalina are not hard to kill, and a center fire .22 is enough. Typically run about 40 - 50 lbs around here.
