My dog is 6 years old, Shes not feeling good, She has had the runs all day and i looked outside while she was going and she had a little bit of blood dripping out. So she will be seeing the vet tomorrow. Her poo is also mucus looking. Can i give her anything to eat that will be easy on her belly? Like maybe rice? And i have some beef baby food also a turkey dinner baby food. Any ideas on what it could be? Shes been sleeping all day too.
