its hard to put your thumb on the average lifespan of a catch dog...i always at least run a cut collar on mine and am looking into the australian chest plates...i like the vests but here in the mid of summer its hard on them....just depends on your hunting style i guess...i like to get anywhere from 15-30 yds out and start walking as soon as i unsnap and when i hear the hit drop it dwn a gear...freak accidents do happen tho take for instance my dog geronimo his granddad jack caught hundreds of hogs in the woods a purty good bit with good teeth and one of the few times we ran a collar and vest on him he got killed along with another bulldog...hog killed 5 dogs total that day
just gotta pat them on the a$$ and say seeya when i get there
