I can't feel them good enough with gloves on to be able to remove them good, I just deal with a little pain and get it done. Now when a dog comes running up to me with 6-8 sections of chulla cactus stuck to their side. I get my pliers out for those.
When hunting in West Texas in the chulla cactus, I carry one of those Afro hair comb/pic in my vest to deal with this bad azz stuff. Control the dog and pick it right out without touching it. Hardest part for me is getting the chulla cactus out of a dog's mouth and throat after they have panicked and bit it. Does anyone have a proven method for that?
