My dog's poo is yellow

[AnotherTry]

For the last month, at least, my male 10 year old dog has had yellow poo. He does not seem at all unwell or unhappy. I'm not aware he's eating anything that would cause this - not helping himself to curry out of the bin etc.

Cause for concern, or not?

Does your dog eat bones? If yes, that may be it (they will also make poop very hard). If not- go to the vets!

What food does he eat?

May be worth a call to the vet ... I tend not to panic unless there are other symptoms, but a phone call wouldn't hurt.
