He was in contact with dog that recovered from kennel cough. My vet only recommends an ultrasound which is too $, other options? He had a sarcoma 2 yr ago & recovered

I would discuss other treatment options with your vet. I understand that ultrasound can often be cost prohibitive, but your vet may be able to prescribe medications based on their best guess of the cause of the illness. Based on the labored breathing, weakness, and gagging, I would be worried about Donny's heart and lungs. I know heartworm disease is not terribly common, but it is still a possibility. Other possibilities include heart failure, pneumonia, hypertension, or cancer. You might discuss radiographs with your veterinarian to look inside Donny's chest. Increased potassium could indicate lab error, renal failure, gastrointestinal issues, or possibly Addison's Disease, or it could be normal. Elevated white blood cells can indicate bacterial or viral infection, inflammation, or cancer.
