This popped up on my FB feed this morning and thought it interesting to share. Although only a small study, some interesting results (I've only skimmed through the study so far and need to read again to absorb the detail ) https://wheresyoursit.wordpress.com/2017/02/13/exercise-dog-reactivity/
I've not read the study yet, but it seems to make sense; we already know that exercise alone just makes dogs fitter (needing increasingly more exercise to wear them out physically), and it's mental stimulation that really wears them out. The added benefits with reactive dogs, I'm sure, would also be in strengthening the bond and trust between handler and dog, which can only be of benefit in anxious dogs.
Thanks for the link. That looks interesting, so I'll read the study. I already walk my two separately each day and Wispa loves sniffing very thoroughly and 'reading' exactly what's been happening before she got there, so it's nice to know that's good for her. Tuppence's sniffing is more scavenging-for-duck-poo!
