I enjoy posts that let others know the outcome: First, Merhow sent me a new door latch for free --so that was cheaper than buying one off line. The parts person I spoke with said that there is no cover or cage for the latch at this time, but agreed there should be.
Second, I took the advice to tie Bob with less rope --he can still reach his hay and put his head down, but he cannot reach the door latch --I don’t have the new one yet, but he can’t reach the old one.
I put duct tape over the latch on the inside --Bob hunted today and it appears that he did not reach or molest the duct tape, so that is what I will do for the new latch --I am also considering making a cover for both latches using heavy-weight fabric or vinyl and attaching with stick-on Velcro --stick on Velcro on the door, sew on Velcro on the cover. If Bob is catching the latch on his halter, that should solve the problem --if he’s eating it --I will put something like “Stop Chew” on the vinyl or fabric and maybe that will discourage him.
FYI Bob did well on his first hunt --much, much quieter as I hauled him with my current hunt horse. Bob loved the company. Usually he sweats in the trailer regardless of ventilation – today he came out completely dry. Yeah! About 10 min into the hunt, Bob’s bridle fell off --I have never seen that happen before! BUT --I did not put his bridle on --the young woman who was riding him did so maybe she didn’t get it on quite properly? One minute it was on him, the next it was hanging by his knees. Bob just stood sill until she dismounted and put it back on him. Then we followed the hounds (second flight) for a couple of hours. Bob had one melt down --not sure if it was him or his rider --but when first flight galloped past second, Bob became agitated to the point where his rider was uncomfortable --so at her request, I grabbed his reins under his chin and pony-d him for about a half mile until his brain returned to his body. I was riding W --my long-time hunt horse (28 this year) who has race-track pony horse in his CV --taking fractious youngsters in hand back to the hunt club has been his job for as long as I’ve had him (22 years). After he settled, Bob then walked quietly the 4-5 miles back to the hunt club.
Thank you to everyone who gave suggestions!
Bob on the field today:
