yellow/green sick

my dog has been sick twice today, its just like a yellow/green fluid...he hasn't had anything different to eat, everything is exactly the same. anyone or your dogs been sick like this before?

thanks

has he been chewing a toy or something i had this with a dog once and it turned out to be a blockage in his intestine , dont want to worry you it might not be the same but if it carries on i would go to the vet after one day

only thing i can think of is yesterday he was rolling around on the field eating grass, and today hes been sick, he still seems his usual self

awww .. the only time my dog has been sick and it has been yellow in colour was when he had an amount of scrambled egg with his worming tablet .. he has never done it since .. greeny colour can be due to grass intake maybe? im unsure on this one.
Hope his well soon!

mine was when he got some dried food which he did not digest stuck in his intestine hard baked meat and the sick was more yellow than green

Yellow/Green sick is actually bile and would need to be investigated if its also very frothy. Otherwise you could try giving a Rennie. Bile can sometimes be caused by going a long time between meals. As long as he seems well in himself and is eating and drinking plenty I would wait and see how it goes. Hope he will be better by tomorrow.

i agree about the bile thats what mine was doing
