Yes, heart murmurs in dogs are hereditary. Generally any heart problems that the mother or the father of a dog has is usually passed down to the puppies.

On the contrary, exercise and activity are good for murmur dogs. They leaner and more fit you keep them, the less strain on their heart. As long as he is not wheezing or lethargic, I wouldn't worry. Sometimes puppies can even grow out of heart murmurs, or so I've heard. I'd like to add, make sure you take care of his teeth, as there is a connection yucky teeth and heart problems.
Yes, a dog's weight can influence its heart rate, as larger dogs generally have slower heart rates than smaller breeds. Heavier dogs may have a lower resting heart rate due to their larger heart size and greater overall body mass. However, factors such as age, fitness level, and health conditions also play significant roles in determining a dog's heart rate. Therefore, while weight is a factor, it is not the sole determinant of heart rate in dogs.
