Last July, the FDA released an alert for veterinary
professionals and pet owners regarding reports of dilated cardiomyopathy (DCM)
in dogs that head pet foods contain peas, lentils, other legume seeds or
potatoes as main ingredients. The
reports were concerning because DCM was being noted in dogs not typically prone
to the disease. “While there has
historically been some evidence of diet-responsive DCM in some breeds (golden
retrievers, cocker spaniels, Newfoundlands, Irish wolfhounds, and Saint
Bernards) the incidence of DCM in these breeds has appeared to increase when
they were fed grain-free, vegetarian/vegan or exotic ingredient pet foods,”
explains WSU professor O. Lynn Nelson, DVM, MS, DACVIM (cardiology), who
coauthored the statement, in the WSU Insider.
“Curiously, other cases occur in breeds without a history of DCM or in
very young dogs.”
According to the WSU website, DCM is a cardiac disease in
which the heart muscles become weak reducing the heart’s ability to pump blood
effectively. Disease profession leads to
the enlargement of the heart chambers, possible valve leakage and fluid
accumulation in the lungs resulting in congestive heart failure. Dogs with mild disease may not show clinical
signs, whereas in other cases the condition can be life-threatening.
Some breeds may be more sensitive to changes in nutritional
components in their food, which may suggest breed-related differences in
metabolism. Alternatively, the balance
of amino acids in some dog food formulations may be inappropriate, or the amino
acids may not be well-absorbed by the pet.
In addition to advising pet owners to always choose a diet
made by a well-established manufacturer, the statement provided several
recommendations:
Healthy dogs should feed a diet
that contains standard ingredients (chicken, beef, rice, corn and wheat)
Dogs that have a medical condition
that requires a nonstandard diet should be fed a diet that has undergone
extensive feeding trials through the Association of American Feed Control
Officials (AAFCO)
DCM related to diet may be
reversible if it is detected early. Dogs
diagnosed with DCM that are eating a diet with nonstandard ingredients should
be switched to a diet that contains standard ingredients as noted above.
