MrsS, I'm no vet. I can only tell you what I do for my girl when she is sick.

Firstly, how old is the dog? Do you know where he/she came from and if all it's vaccinations are up to date?

When my girl is sick, I give her bland food. Rice with some mince ensuring all the fat has been drained. I know a few years ago I gave her a sausage or two and the fat was too much for her body to handle. That was one expensive lesson. Another thing is sowntimes she'll cough a bit and be sick when a raw bone hasn't agreed with her.

Those two times she went off her food and had to go on meds and have the bland food.

The cough i'm not too sure about.

Another thing you could do is to check the dogs stools. If you go to the vet they'll most likely ask how often they have been going and what's it like.

Hope your doggie is okay.
