Love the snow pictures! The dogs are having a good time!
This is a new one on me. First thing that went through my mind, are the ewe in heat? Estrus is estrus and the smell may be making him misbehave.
A guy that we used to get hay from had cattle. he got a jack donkey to protect the calves. Wrong. When the cows came in heat, the jack attacked the bull for trying to breed them. He chased the cows, biting and kicking them. Needless to say, that jack got hauled to auction.
Could be. Maybe a dominance issue, but why now? Pinkie will straighten him out. Her, and the collar. LOL LOL
