I have to agree with minimoo
I've experienced far worse yuck moments with my cocker. I do understand that it is not exactly pleasant to see them eat bugs. But with my cocker, the biggest concern is poop eating. And I am afraid to tell you what kind of poop she seems to be an expert at finding. She also ate a dead mouse off the street once
Not to mention her habit of rolling in anything that smells bad. Last week it was a dead hedgehog, this week a dead mole
