Well new old friend, that is. Mac and Tomato have always been friends over the fence but I never put them out together because I didn't want anyone to get hurt. They are both dominant and show it by kicking out at the other horse (but not people!).
I decided, though, that I didn't want Paddy to keep getting pushed around by Mac so I put Mac and Tomato out together. It was so uneventful I couldn't believe it. They sniffed noses, then shared a pile of hay.
And that was it. They are good buddies and like to hang out together. Without much pomp and circumstance it was decided that Tomato is on top, then Mac, then Paddy.
