Summary:
Medical records were reviewed for owner and cardiologist submitted cases of dilated cardiomyopathy in pit bull type breeds. This is a retrospective study, meaning it "looked back" at existing data, and it was a multicenter study, meaning that the dogs included in data analysis were diagnosed and managed at different veterinary hospitals.
112 cases were submitted for inclusion, and 21 were excluded for a variety of reasons documented in the full paper. This left a final pool of 91 cases for analysis. 7 of these cases were from outside of the USA (6 in Canada, 1 in Germany). Of the 76 dogs with known diet history, 84% of dogs were eating non-traditional commercial diets, and the other 16% were eating were eating traditional commercial diets.
