Its a normal way from them to bring up bile from the stomachs, although they do tend to do it far more often in the warmer weather.
It's because there's more about to eat .
i've noticed dogs have they favorite patches to eat. which is strange you'd think it would all taste the same to them but they do like fresh sweet grass.
anyone else's dogs do the same?
My bitch will go to the same patch of grass every time and have a good chew.
