Evaluation of Lung Ultrasound for Diagnosis of Congestive Heart Failure in Dogs Presenting with Cough

Area of Study: 

Purpose of Study: 

The purpose of this study is to determine if lung ultrasound will be a useful addition to the diagnostic evaluation of dogs presenting with cough. Causes of cough in dogs include congestive heart failure (due to primary disease of the HEART), as well as primary disease of the RESPIRATORY system (lungs or airways). Lung ultrasound is a new imaging modality that can help to differentiate these two types of diseases so that dogs can receive an accurate diagnosis and appropriate treatment. Additionally, lung ultrasound is faster and less expensive than a common test used for this purpose (chest X-rays).


The study is open to any dog with a history of cough (for any period of time and any degree of severity). Your dog must already have an appointment with the Lloyd Veterinary Medical Center (with any service; the appointment could be specifically to evaluate the cough, or could be for any unrelated reason). Finally, your dog must be getting chest X-rays during the visit.

Client Responsibilities: 

If you agree to have your dog participate in this study, the participation will be limited to a single visit.

A veterinarian will perform a lung ultrasound is examination while your dog is gently restrained (either standing or lying down). Some of the hair on your dog’s chest will be wetted with alcohol (no hair will be shaved) and the veterinarian will hold an ultrasound transducer up to the side of his/her chest to obtain images of your dog’s lungs. The lung ultrasound examination lasts approximately 2-3 minutes. The rest of your dog’s visit will be unaffected by this study, and participation in the study will not add a significant amount of time to your dog's visit.

Client Benefits: 

Participating dogs will receive a lung ultrasound free of charge ($40.00 value).
