We have an 11mo BC and she is generally a delight. Bit nippy when younger but incredibly affectionate, soppy and obedient at home. She goes to specialist daycare and has two dog walkers who she adores and 98% of the time she’s a dream. However she is a bit reactive on the lead on narrow footpaths when approached by other dogs. My husband took her along the towpath earlier today, and when passing other dogs that bound up to her she gives them very short shrift and is a bit growly and snappy but only once and then will move along without incident. She never bites them, it’s a warning. She also NEVER approaches another dog, ever. But dogs jump up to her and she doesn’t like it and she looks aggressive in return. She also barks at children running past but I’ve been working really hard on that and it seems to be improving (taking her to busy places, sitting, watching and being given treats for not reacting to triggers etc). Does anyone have any suggestions of more we could do? I know some of it is her breed and her nature, but it would be good to help if we could. Thank you!
