Last evening when I took Doc for a walk, we were walking by my neighbor's who has two, almost two-year old, unneutered male Great Danes and their mother. They are on a three acre fenced property with an automatic gate for the driveway. Just as we were approaching the gate, someone in a car opened it to go in, and the dogs ran out and started circling us and barking. The two males stayed back a ways but the mother was coming in, growling aggressively and I kept kicking her over and over and over each time she tried to bite Doc. I even fell down at one point. The lady who was driving the car was standing their yelling and trying to keep the dogs back. Then someone else at the property came running and they finally got the dogs back into the yard. It could have been disastrous so I'm thankful that nothing really happened and the other people were there. It wasn't really anybody's fault. The dogs stay in the yard just fine when the gate is opening for a car or horse to go in and out, but, they wanted to get to Doc. They always run up and down the fence barking furiously when we walk by. I really don't know why my neighbor is keeping both males intact. :? She's not a breeder, although, she did breed the mother once. It sure was scary.
