This may turn into a long story. Had my dogs on the heath this morning and as usual, they like to go say hello to all the other dogs. I am always careful about letting them both go up, as they can be intimidating. This morning there was this border collie and for the first time in months, Ferdie tried to mount him. I grabbed his collar (not easy with all that fur) and got him off straight away, the collie growled and snarled at him and this is where it gets unusual. Every time another dog goes for Ferdie, he will run back to me. This time, he started growling back. I pulled him away and got his lead on, led him away, but all the time he was looking back and whimpering to get at the collie. This is so unusual for him. Now I think I am going to have to keep a brightly coloured lead on him (so that I can find it in a hurry with all that fur) just in case it happens again. I don't want to just keep them away from other dogs, as that rather makes the situation worse, but I need to be able to get this under control in a hurry. I cannot risk a fight with a dog this size. I have been racking my brains and this is the best I can think of. I could just keep his lead on, but again that would not be easy when there are lots of other dogs around. Sometimes if he has his lead on on the heath he just does not want to walk at all. Does anyone have any other ideas?
