Q. Black mouth cur 1yr walks on leash finds spot in bushes lays down and does not want to get up adopted pet w/upper respiratory infection
DESTINI R. HOLLOWAY, DVM
A. It sounds like your pet may not be getting enough oxygen delivery to the lungs or is over-exercised. If your pet has a previous history of respiratory disease that also affected the lung fields and by just the upper respiratory system then it is very plausible that the lungs may have some permanent damage from this precious insult and are not as effective at oxygen exchange. I would have thoracic radiographs done to check the lungs and make sure they are ok and don't show signs of chronic change.
