Hey all, so I am a long time horsewoman but have recently run into an issue I have never had before. So You may remember I bought a 7yr old reg paint mare for my 12.5 yr old DD to move up to from the 19yr old morab. Have had great luck with the mare, already gone on Judged trail ride and several shows with NO issue. I am definitly the bad cop for DD's mare. Really the bad cop for all the horses. They KNOW and respect my word. So we have had new paint mare for 3/4 months. She was "profesionally" trained at some point. Sold at a reg paint sale, and the guy I bought her from had her for about 2 years and rode her like maybe 10 times in 2 years. SO he decide din this economy to sell her. I didn;t ask as I didn't think it important but I don't think she had ever been fed treats by hand. So this last week I went out to deal with an injury My horse has and here comes paint mare. She sees me give my girl treat to put leadshank on her. I tie her to fence post.I push paint mare away and , she insists on getting in and around my way. I keep pushing her away. I finish with my girl and give her another treat, and turn her loose. Here comes paint mare, now with ears back and trying to crowd me to fence. I smack her and yell, and she leaves. Next day I go to treat my girl, and now paint mare is back and more insistant because she KNOWS I am going to give my girl a treat. Again I push her off and smack her. Next day, DD is with me and she plans to ride so she goes to get paint mare, and that is no problem she gives her a treat and OMG she practically gulps that thinkg down and she is lipping DD's fingers, even though she has a FLAT hand. Yesterday I go out to deal with my girl and my son goes to mess with the morab (dd's old pony) Paint mare tries to crowd HIM cuz she KNOWS he is going to give morab a treat. Giving a treat was Standard to reward for easy catch till now. I never had an issue with more than 50 different horses. SO because she is trying to crowd son, I go out with dressage whip and tell her NO. SHe sees whip and backs off, but THINKS about going around me. NOT happening. This morning I have to catch and tie the 3 because hayman is coming and he drops round bales in pasture. Get my girl first no problem as she is top dog. Go for paint mare next, and GIVE her a treat, Flat hand and STILL she lips my fingers and PINS her ears!!! I tie her and then lastly do the 19 yr old morab. SO I am for the first time ever seeing how it CAN be a problem. SO I am torn on what to do. If I stop giving treats, my girl would be fine, but 19 yr old morab, would be MUCH harder to catch. DD at 9 "tricked" her with the have something, opps your bummin". SO I have made sure to ALWAYS give her a treat when I catch her. SO my son and I can catch her but DD can't still to this day. I guess I got to catch paint mare and tie her THEN catch morab and give her treat. Would really just like to get Paint mare mellow with the treats. She wasn't this way in the begginning. It happened after she asserted herself to second place. SO do I just give up the treats? Paint mare is aggressive, pins ears pushes and tries to crowd you AND then is snappy/mouthy when taking the treat. I have NEVER had this issue before. Any advice?
