Can a diet change help with Diet-Related Dilated Cardiomyopathy ?

An 11-year-old intact female Papillion weighing 2.1 kg was presented to a veterinary clinic with signs of shallow, rapid breathing.

Through transthoracic radiography and echocardiography a clinical diagnosis of dilated cardiomyopathy (DCM) was made. The dog was treated with pimobendan, temocapril, and taurine and later furosemide because of fluid buildup.

The dog had been fed a diet that was identified as being related DCM by the U.S. Food and Drug Administration. The dog’s diet was changed from a grain-free diet to a grain-containing diet.

On day 1191, the patient's respiratory status was stable and no clinical signs were observed. Transthoracic radiography and echocardiography revealed an improvement in left heart size. Additionally, improvements in the left and right ventricular myocardial strains were observed after changing the diet.
