Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 4 years and 9 months old | 45 lbs
My rescue dog Bella, was treated for heart worm and is fine now. She seems to pant when running, as if she is out of breath. 1. Can this be a result of her having had heart worm? 2. I had a boxer (70 lbs) who took L-carnitine 250 to prevent heart problems prone to this breed. (He lived to 11+ and died of cancer.) Will this also strengthen and be good for Bella's heart? 3. If yes, what would you recommend for a 40-45 lb. dog? Thanks for any advice you can give me.

Unless she has any ongoing heart disease or is a breed with a genetic susceptibility to heart disease, this supplement is not likely needed. I recommend to discuss using the supplement with your regular veterinarian as they are most familiar with Bella and her history. Best of luck and please feel free to post any additional questions.
