Hi. Well I'll start at the beginning. I have one staffie and one collie/greyhound mix (Nisha). She is a rescue dog whom we got last year. I started by walking them separately for training purposes and recently she started playing wonderfully with other dogs and would run around with them playing happily for hours! In January my staffie (Keira) got attacked and I had to work hard on her walks to resocialise her which recently succeeded. So my next plan (a little later then originally hoped) was to walk them together. Over the past few days I have been getting them used to it without distractions around (other dogs). Today on the way to the field a man and his dog was coming up the lane, I couldn't avoid it and was grateful that it was one that they both knew. .. Unfortunately nothing went well.. they both attacked (much to my shock!) . I think it was Nisha that instigated it as she reached the dog first and Keira reacted next. I managed to get them under control before any injuries would occur. But what I can't understand is why they would do that to a dog they normally would be pleased to see on a normal day (when I walked them separately ). They haven't shown any signs of anxiety with the group walk otherwise I would have stopped the group walks altogether. Does anyone have any advice and does anyone else have any experience in this?
