OMG!!! Sorry that you had to cut his mane, but hey, it will eventually grow long again and I really think that a short mane fits your horse quite good. Just wait until it's grown a little bit and your horse will look great again!
Wow, are those the prickly little burrs that have the hooks on then end of each spine that it takes about a month just to get one out? YIKES!! How is it that he managed to find the entire patch and the sorrel didn't have even one? LOL. I am sorry that you had to roach him but it is just hair and it will grow back out eventually. :)
Cockle-burrs I have a major OCD about them growing in my pasture. I run out with a herbicide and spray them dead whenever I see them. Major bane to horse owners. If you drop one of the little nasty seed burs on the ground 5 will grow in its place. I always toss them in the trash when I find one.
Oh no!! That happened to me except it was my horses tail!! Next time before you jump to cutting it, try the old trick of peanut butter. Or get a huge bottle of conditioner and let it sit in his maine all night. It will work trust me!
