So I'll preface this by saying he is of course no longer allowed off lead.
Our 22 month intact male cavapoo has gradually been getting more crazy since the autumn started. Where before he would just have a small run around us (when let off lead in the park) he started going further in the woods but still coming back to us. There was a lot of barking at squirrels and trying to climb trees after them etc.
However, this week on two separate occasions in two different parks, with both me and DH, he went completely crazy running around and not listening at all.
In the park yesterday he just started running round the entire park, paid zero attention to me and nearly ran out of the park into the road. Only stopped to say hello to someone who kindly grabbed him for me.
Does anyone have any suggestions as to why he has suddenly started doing this? Obviously his recall is going to need a lot of work and I need to stop letting him off lead as its reinforcing his behavior (thrill of the chase etc) but is it just the squirrels, his age, his hormones, maybe a dog in season (but its in multiple locations)? I'm a bit stumped as to why he is regressing rather than improving.
