Is there one drug that is better than another for a small case of heart murmur. I have had a less that 2lbs 12 year old chihuahua. It's case is not that bad. Other than that the dog is in over all good con. The dog got to me as a stray. It has no other problems. And it's blood test was neg. for heartworm. What do you suggest?
If your vet did not recommend a heart medication for the murmur then I would not worry. You can always get a second opinion from a cardiologist. vetcare
