Let me start by saying I know practically nothing about horse care. Occasionally, I drive by a group of horses whose mains and tails are constantly tangled in burrs (from weeds). I've been driving this particular route regularly for a few years, and the burs are there across all seasons. The burrs in particular are common for the area. My dogs sometimes get them and I find that they need to be removed immediately or else they become so entangled that it interferes with movement or contorts their tails in unnatural ways. I'm concerned that the constant presence of burrs on the horses is evidence of a lack of regular grooming, which may be evidence of neglect and possibly abuse. Today, I was driving by once again and had my camera in the car so I stopped to take some pictures. I know these allegations are serious and many people may object to "sticking my nose" in other people's business. So, I am posting here to learn if this kind of thing is generally considered acceptable to people who know things about horse care (i.e., this community). Is this ok?
