Connected

Have you ever had a horse so connected with you that she or he acts jealous of others. Not people, but other horses or animals. I lovingly refer to Misty as "my pissed off little pony". I bring this up, because today I spent a little extra time with the girls as I needed to top the water off in their trough and it wasn't so bone chilling cold that I spent the extra time with them, clearing winter eye boogers and removing their halters again and clearly my previous post made all a bit uneasy.{{Sorry}}. I removed Misty's first and as I turned to remove Kola's, Misty reached around to bite at Kola. A behavior I disapprove of while I'm in there and standing in between them. I quickly corrected Misty and she stepped aside. I then turned my attention back to her when I was finished with Kola and she tried to give me the cold shoulder. I softly talked to her and she lowered her head and let me close. I try to give equal time to both, scratches and a little massage. As I left the pen, Fido the dog was lurking between the horses. He always does this. Anxious to get to the horse apple buffet. I was still talking to Misty over the fence and I started to talk to Fido. Misty then reached down and nipped at Fido. I verbally scolded Misty a bit and told Fido to get out from the paddock. Misty then began licking my hand. I promised her she would always be my number one, I whisper that to her all of the time. I just find it amazing that she is that jealous or at least it seems this way. It doesn't translate to poor behavior when I do things with her, ground work, saddling, riding. She is by far the most trust worthy mount one could imagine. Are we that connected? Or this something else? She's always a bit crabbier during the winter as I think alot of horses are as they miss the pasture and the time spent. It's cold here, so the time spent with them, even though it is daily, isn't as much as it is during the warmer months for obvious reasons.
