I have 4 dogs and having a pony in the pasture is new to them. One of them got kicked in the head and now never tries to get into the pasture. I have one dog who is scared to even look at Smokey LOL but i have two dogs that like to go into the pasture and eat the horse poop. One gets weird if smokey goes up to him while he is eating, kind of circles the pony and barks and shows his teeth. I dont' think he would ever bite him. But I have a Bull Mastiff that will eat anything, just recently ate one of my chickens....whole think, bones, beak, feathers and all. She goes in and eats poop too. I am concerned of what she would do if Smokey went up to her while she was eating. I try to keep the pasture cleaned up, I toss the poop in the field behind our pasture, but I am still concerned. I don't know if Maggie (My dog) would or could take down Smokey. I don't know what to do or if any of you have ever had a dog that has gotten ornery with their pony or horse.
