Puppies can have what are called "innocent" heart murmurs that they outgrow. She could also have a very serious heart condition. You won't know how serious it is until she is seen by a cardiologist as the vet suggested.

I don't know what your financial situation is, but you could be looking at some huge vet bills with this puppy. She is also very small for her age. She needs to have a bile acids test done, too.

As Yorkiedaze suggested, you might want to contact a rescue group if you are not able to care for her yourself.
