Why is my pet vomiting?

Why a pet vomits can range from dietary indiscretion (garbage enteritis) to more life threatening causes like bloat or foreign body obstruction. The most important thing is knowing when calling your vet is not optional anymore.  When we have someone call our hospital about a vomiting pet, we use the frequency of the vomiting and the ability (or inability) to hold down even liquids to help us decide.  If your pet has vomited more than 8 times and cannot even keep water down, especially if he/she is acting lethargic or non-responsive, it is time to seek emergency medical help.  Only a veterainarian,with the help of experience and diagnostic testing, can truly decide what needs to be done. Fast medical assistance may be the difference between life and death in some cases.
