Same thing here. My dogs are all trained not to go into the pastures, so they sit by the gate and watch.My donkeys know my dogs and will come up to them at the gate, and everything is fine, but if they would be inside the pasture..I wouldnt trust my donkeys with them. My donkeys will chase any dog, cat or whatever happens to come into THERE pastures right on out! I have them to protect my horses and they do exactly that. I have 4x4" square fencing, so that helps to keep everything out. Even if I have a donkey stalled and a barn cat goes into there stall..they will chase it right out. I did lose 2 kittens about 12 weeks old last year, to a donkey who stomped them..right in her stall. They are very protective! When I have one on a lead or tied up outside of the pastures they are fine, with dogs and cats. Corinne
