Just did mine out of warranty and $89 and 14 days got I back.

yes it is required

Just went thru that with my cur. cut was on the rear leg, cut vertical slice thru the muscle for 4 inches, used chromatic (catgut) suture  and sewed up the muscle and regular mono for the skin. It was deep and long and could not sew all the way top of the cut but he's healing good. Course if the cut was cross the muscle it would have been a different story. My other cur took one behind the last rib and all the way to the intestine facia but i took him to the Vet, he did the same thing, catgut for internal and and staples/ mono suture to the skin.

I've hunted the ranch for 4 years 3x a week and good dogs with training will not trash on deer. I have not seen any movement difference on deer patterns all year long. The ranch is commercially hunted and all I dop is not run dogs 2-3 days before hunters arrive. I have spent my career studying deer and more disturbance is happening when they are actually hunting deer. I have had the owners family out while i have been hogging and they seen how my dogs work, and they see my dogs run right by deer and the deer stand there. Axis deer are more wary of human disturbance and hunting pressure than any other animal and the ranch has been more than successful in getting clients on trophies.  As i said before actually hunting the deer is more disturbing than hog hunting. The deer know when they are hunted, you can see the interaction when you enter the field and go to blinds. A little shooting at deer changes the whole dynamic. my landowner is very happy with my control of feral hogs. He encourages me to kill more and hunt more often, he can see the benefit of not seeing the damage and not seeing the hogs when they hunt. Best of all hogs are not disrupting the hunt for the clients. I kill 40-60 hogs a year off this place and barely keep them under control.

Had my 8 m/o cut like that with one hanging. Tried stitching him up but he washed them out. Decided to let close up on its own, some stitches stayed and held it both of them in. It closed up but had to watch him for infection. Kept him on a regime of antibiotic every other day for 5 injections and kept it  clean. It healed up and he's a great BMC and I'm hoping he's got the juice to makes some pups later.
