Not only do most of my dogs eat poop (except for the pitty-girl Mica), my oldest Terv likes to bring in poopcicles in the winter time, to chew on at her leisure.
Well I'm glad I'm not the only one. We have lots of jokes about it, 'the dogs are eating popcorn again', the chickens are 'popcorn machines', the dogs are 'vacuuming the lawn again'.
Regarding the nausea, I can say that one of my poo eating dogs has food allergies, and he has mild allergic reactions after he feasts on chicken poo. Chicken food is unfortunately LOADED with the things that typically trigger food allergies in dogs - soy, corn, wheat, grains, etc.
I have found no other solution other than keeping the chickens (mostly) away from places that the dogs have access. I allow a little poo eating as long as the allergies don't get too bad.
My vets have also told me there is no harm in the poo eating, other than monitoring the allergic reactions.
my puppy stays in the kitchen away from the cat for now, and she got into the playroom and guess what she found? cat puke! yum! so she started to eat it. at first i was like 'ew josie, that's so gross...' until i remembered that i was the one that was going to be cleaning it up...then it didn't seem all that bad. lol don't worry, i didn't let her have it...ew
