Hi,,, We have 2 four-year-old Yorkshire terriers (male and female) and we are trying to introduce them to other dogs. Our neighbour is kind enough to let his female Labrador 'try' socialise with our dogs. She is super super submission and goes straight to the ground. Our female seems not to be fussed with her and gives her a sniff but our male stands over her and wants to bite her. All three of us went to an open field, which is where all the dogs and owners meet. And everyone lets their dogs off the lead. It is truly embarrassing when you have these 2 Yorkies that we have to hold down, as they want to attack all these happy dogs. And might I add some really BIG dogs. I don't know how we can get them to get better at it. Do we keep going to the field and hope they will start getting along with these dogs? Do we nozzle them and then let them off the lead and see what happens? It is almost like having naughty children and we are the embarrassed parents. Any advice will be welcome.
