I am sorry to hear about your dog. These symptoms are indications that your dog needs to see a vet right away. Any time we have breathing issues, it is considered an emergency. There are many different causes for lethargy and difficulty breathing but could include an infection in the lungs, a problem with the heart, anemia/low red blood cells, trauma to name just a few. The vet will do an exam and may recommend x-rays of the lungs and/or bloodwork to check for low red blood cells and signs of systemic disease. They may provide oxygen support if needed and will base treatment on the results of testing. I wouldn't delay in getting her in right away!
