My dog ate marshmallow peeps?

she'll be fine, maybe have a stomach ache but she wont die or anything. my little shi tzu ate a whole bag of chocolate chips when he was a puppy and surprisingly he's still alive. But if you are really concerned about your dog, bring her/him outside. when dogs have upset stomachs sometimes they eat grass to make themselves throw up. at least it will get all the marshmallow out of his system.

Unless she has a history of blood sugar issues, she'll be fine. Probably have an upset stomach and a bit of diarrhea... make sure you take her out a lot. But yeah, she'll be fine.

she will be fine, dogs love sweets, beware of chocolate, it damages the liver, and Raisins raise iron levels, both can be fatal, but there is nothing in peeps that I would be afraid to feed my own dog.

She should be fine - Nothing to worry about, she might be sick and poo everywhere but if this persists you should probably call the vets x

she will probably get sick and maybe throw up, she may exhibit some erratic behavior from all the sugar but she will probably be ok.

Sugar overload. Keep an eye on her.
