Jane. In answer to your questions on my dogs behaviour on seeing vis vests & cyclists.
The dogs are off leads when this situation occurs. But they will run a good few hundred yards across a field to get to the cyclists. When they get to the cyclist they stand off a few yards & bark continuously. The first dog to see the cyclist will take off, with the other in close pursuit. I have no fears that they would attack anybody, but I dont want any accidents or cyclists getting hurt falling off. They didnt have much obedience training.We joined a local puppy class, but had to stop going because they were disruptive. They wanted to play all the time. But over a period of time they have become quite obedient. They will come when called or whistled. They will sit on command, and stay on request except,when they see a cyclist with a vis jacket. As regards what we do when we get to the dogs, Leash them,apologise to the victim. They also get no treats for the rest of the day. They are not bad dogs and we love them dearly, but we have a problem we want to do something about before a cyclist or one of our dogs gets hurt. We would be grateful for any advice you could give to us. Thank you jb.
