We have a 14 year old Boston Terrier that has been diagnosed with Cushing’s disease. She had heart worms about two years ago but has been heart worm free since then. She sits in front of a fan, has problems running around being an active dog. She seems to be always hungry. In the last few days, she has had serious problems with breathing, her tongue turns blue. We had her checked out by a local vet and he says she has a strong heart beat, no heart worms and Cushing’s disease. We are trying to understand what is going on and how everything ties together.
If your dog is having difficulty with breathing and is turning cyanotic (blue) this is a very serious medical condition. Chest radiographs are critical to rule out pneumonia, cancer, and heart failure to name a few. Pulmonary thromboembolism (blood clot in the lungs) would be another concern. If an immediate cause cannot be identified by your primary care veterinarian, discuss referral to a specialist to help determine the cause for the respiratory problems. Again, this is a most serious problem you are describing and immediate attention to this is needed.
