My dog has a habit of licking bird droppings and yesterday he was sick and had brown watery poo, today he has blood in in poo, do you think this is associated. Thanks

Nope but u should still bring it to the vet! X

It is unlikely that the bird droppings caused it but as kate said you really need to get your pup to the vet, blood in the stool is not good.

Bird droppings can carry the parvo virus, is he up to date with vaccines?
