Dog X-ray showing early heart disease in an older dog

Do You Know the Health of Your Dog’s Heart and Lungs?

May 1, 2018

Your dog just had a complete senior blood panel done and it was perfect. Now, all of a sudden, he has started to cough at night, especially when she is deep in sleep on her side. What’s going on? Shouldn’t the blood test have alerted you to this! Unfortunately, blood work tells us nothing about the heart, lungs or anything else in the chest. Heart, lung and tracheal (windpipe) health can only be determined by x-rays. After 8 years of age your senior dog needs to have regular chest x-rays to identify potential problems before symptoms (coughing, panting, decreased energy) occur. So, what do x-rays tell us about the chest?

-Heart size. It is common for older dogs to develop poor functioning heart valves that cause regurgitation and murmurs. This “un-pumped” volume of blood causes the heart to enlarge and become less effective at its job of circulating blood. This size change can be spotted on x-rays. Treatment, western and eastern, can be started to support heart health and delay or prevent eventual heart failure.

-Lung clarity. The blacker the area of the lungs on x-ray, the better. Allergic bronchitis, bacterial, viral or fungal infections cause fluid to accumulate in the lungs, decreasing air in the lungs. This causes the lung x-ray shadows to become greyer, rather than black, indicating a problem. Tumors or growths also show up as grey areas on x-rays. By knowing there is a problem, tests can be done to identify the cause and treatment initiated.

-Tracheal diameter. That dry, “honkey cough” by your dog when she gets excited is probably due to a collapsing trachea, especially if she is a small breed dog. X-rays clearly highlight the trachea, so when there is a constriction due to collapse or other problem (allergic irritation, inhaled object or growth) they are easily identified. The proper course of action can then be taken.

And, believe-it-or-not, we can generally identify problems in the chest with just 2 x-rays- one from the side and one with your dog on its back.

Your dog’s chest health is important. To help you learn more about your dog’s chest health, we are offering 10% off any 2-View x-ray study during the month of May.

Future blogs this month will highlight problems in other parts of the body where blood work won’t tell us anything and x-rays can help.
