Despite these shocking numbers, owners are still oblivious to the fact that their Chi could develop heart disease. Heart disease for us means smoking and fatty diets put us at greater risks, for Chihuahua’s and other dogs it’s much more complicated. In fact, the most common form, valvular disease, affects mainly smaller breeds over five-years-old.

Many Chihuahua’s will be prescribed either furosemide, enalipril or vetmedin and all of these are known to cause an upset belly. Some Chihuahua’s will require blood thinners, some will need blood measure medications, and others may only need supplements. No matter what medication your Chi is prescribed, consistency is essential to proper treatment.
