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!

    Oh, poor Buddha! Yes, I'm afraid that I would consider this an emergency - he really needs to see a vet tonight, so I would definitely call your husband and make arrangements to take him as soon as possible. Heavy or labored breathing along with acting very lethargic is very worrying - he may have severe heart disease, fluid in his chest cavity, a severe respiratory infection such as pneumonia, lung cancer, or even internal bleeding into his lungs or chest. This is likely to be a life-threatening problem, so he needs to be seen by a vet as soon as possible. The emergency vet can do chest x-rays or other testing if needed to help determine what's wrong and see what can be done to help him.
