Investigation into Subclinical Diet-Associated Dilated Cardiomyopathy in 4 Dog Breeds
Dilated cardiomyopathy (DCM) is a serious disease of the heart muscle whereby the heart becomes enlarged with weak contractions. Recently, veterinary cardiologists have recognized DCM more frequently in all breeds of dogs, not just breeds usually associated with DCM. There is suspicion that the disease in some dogs is associated with boutique, exotic ingredient, or grain-free (BEG) diets. The extent of the problem is unknown and therefore this study intends to screen a large population of apparently healthy dogs of 4 breeds (Golden Retrievers, Doberman Pinschers, Whippets and Miniature Schnauzers) for DCM to determine the effect of diet type on heart size and function.
Clinically healthy dogs will be included. Owners will provide a dietary history and allow for echocardiographic testing and blood sampling. Any dogs that are found to be affected will be offered 3 additional visits over the period of a year if they agree to change the diet of their dog.
Owner's Responsibilities (Samples and Information to be collected):
Owners will provide a diet history and allow for echocardiographic testing and blood sampling. Serial rechecks will be offered to any dogs that are found to be affected if a diet change is agreed to. Travel to one of the screening sites is the responsibility of the owner.
- a. Whippets were screened at the American Whippet Club National Specialty breed show in Topeka, Kansas April 16-18.
- b. Golden Retrievers will be screened at the University of Florida (Gainesville, Florida) or the University of California, Davis (Davis, California).
- c. Doberman Pinschers and Miniature Schnauzers will be screened at the University of Florida (Gainesville, Florida).
