Have you noticed your dog acting strangely?  Has his appetite waned?  Have you heard him sneezing or coughing?  Has he started having accidents in the house even though he’s housebroken?  It’s important to watch for signs of strange behavior.  That doesn’t always mean a trip to the vet.  Sometimes, a tummy ache and soft stool can be cured with something as simple as boiled chicken.  I find it best to keep at least one of the following items in my house at all times: chicken and chicken broth.  I find it best to boil the chicken and pour the (cooled) broth over it when it comes time to serve it to your pet.  For those days when pet food is too harsh, I will give my pets a strict chicken-only diet until it clears up.  It is rare that they don’t start perking up in a day or two.
