Chat reaches more people than the doghouse.
Unfortunately a small pug was killed by a larger dog in Wolverhampton today
(loads of people tried really hard to intervene) It's also happened a couple of times near me (in Greenwich park and Crystal Palace park)
This happens occasionally and if you see it happening stick your fingers firmly up the anus of the dog being aggressive - they will very likely let go.
It's not fun, it is revolting. But it may save a dogs life if more people know about it.
