That Montana picture; we’re her front Legs swollen a bit? Looks a little stocked up to me. I have a 7-8 year old gelding mule and yes they love to paw. Expressing frustration I think. He will take his hobbles off in about 5 minutes unless you have them on way too tight. Then it takes him a 1/2 hour…. Gave up. Tie him high and not too tight so he can step around a bit and he soon settles in most situations.
He is a rough country Cadillac and I have him walk trot loping good enough to get a ribbon in the local horse shows. Changing leads stopping and turning around too. Covid wrecked the show season but hoping for next year to win a Reining or two.
