DDog is a 13 month old ~arsehole~ Scottie cross cavapoo, or mongrel as I call her. Accidental mating much to my friends horror. She's been exceptionally sociable from day one and loves other dogs more than anything, but is partial to other people too. I've often joked that she'd quite happily piss off with anyone that would have her. We had 1:1 training and she's very capable, but recall continues to be a real issue because as soon as someone else or another dog is near, she's gone, and does not come back. Due to this, at present, she's on the lead at all times, except when we get to the local dog field and she goes off to play. She basically runs herself so ragged that catching her is easy. She's affectionately known as the friendliest dog in the town and whilst she gets told off by other dogs occasionally for being too full on, there's generally no problems. That sets the scene.
I took her to the field the other day and there was a pair of sibling cockerpoos. They're a similar age and unfortunately the owner really struggles with them. They seem to struggle to play and bark at the other dogs all the time. DDog was enjoying a play with others and one of them kept barking at her, very close and in her face. The next thing I know and DDog turned on her, no biting, but proper gnashing, barking, growling and pushing. She's not very big but clearly this bothered her not and whilst the other dog was going back at her she continued to stand her ground. I shouted for her to come ~still deluded on that one~ and she moved away from the cockerpoo and continued to play with her friends. Cockerpoo was put on their lead.
I've never seen her like that before, I suspect she was thoroughly pissed of with Barky McBarkface twins and so made it known but what should I have done/do/look out for in the future? Should I be concerned at all? For reference, my previous dog was a class A wimp who always came back, so this is new territory. Apologies for the essay.
