Indicators of congestive heart failure in elderly dogs: Occurrence and associated risk factors study in the hilly state of Himachal Pradesh
Keywords:
Canine, CHF, ECG, Geriatric, HeartAbstract
The present study was conducted at Dr. G. C. Negi College of Veterinary & Animal Sciences, CSKHPKV, Palampur, to evaluate the occurrence and causes of congestive heart failure (CHF) in geriatric dogs from June 2023 to August 2024. The total number of registered dogs was 2,574, out of which 275 geriatric dogs were screened and 24 were diagnosed with CHF, reflecting an occurrence rate of 0.93%. Dilated cardiomyopathy (DCM) was the most common cause (37%), followed by mitral valve disease (MVD) (29%). Labrador Retrievers and non-descript dogs were most affected. CHF was more common in male dogs (75%) and in dogs over 15 kg. DCM predominantly affected medium to large breeds, while MVD was more prevalent in smaller breeds and these findings highlight the need for early detection of CHF, especially in breeds prone to specific cardiac disorders.
