Ohhh!!! I so love your baby. "Goof Ball" and my Taco could be friends.
Taco is a sweetheart! Funny, one of my boys refers to my Tango as "Taco"
How old is Tango? Are you sure he's not just having those "backwards sneezes" dogs get sometimes? Mine does once in a great while and I remember when Pickles had them, too.
Rose, thanks for the reference, I appreciate the time you took to research. I've dealt with reverse sneezing with both my dogs their whole lives. It, and tracheal collapse, are very common maladies in little dogs.. And it's even worse in brachycephalic dogs. Tango's snout is longer than the breed standard calls for, so at least he's not hampered in that regard. Even so, Tango in particular has always had episodes worse than Jazz, my other chi. We've never known why that's so.
Tango is almost 11 by the way, to answer that question.
The X-rays show that his heart is pushing against his trachea, but whether it's always been that way or is a recent occurrence is unknown. His heart is large, hence the pushing, but that's typical in tiny dogs (Tango's 3.5 pounds)...there's just not enough room in their little bodies for all their organs to fit they way they would in a larger dog. Whether it's always been that way, or has become enlarged over time because of those potential cardiac issues is unknown.
My doc can detect noises in Tango's chest cavity that suggest pulmonary issues, and he can hear some heart anomalies too, but the problem is that he's unable to isolate very specific cardiac sounds the way he can in bigger dogs, the primary reason being that in a larger dog he can place his stethoscope over different areas of the heart and hear the way different parts are functioning. In Tango's case, the end of his stethoscope is bigger than Tango's whole heart so there's no way he can isolate specific sounds from different areas.
There isn't a lot that can be done with tracheal collapse. There is a low success rate for placing stints in the trachea to open it up, which is really the only surgical intervention. Other than that, what is usually prescribed is a combination of bronchodilators and allergy meds and the like to keep the airway as open as possible. If there specific cardiac issues, depending on what they are, there's a possibility that meds can at least alleviate some of the symptoms.
If he's heading towards congestive heart failure, which is my fear (and there are indications of that because of the pulmonary issues and the anomalous heart sounds) then there's not much to be done in the way of treatment. It's a progressive disease, just like in humans. Treating the symptoms and slowing the progress is the typical approach.
I should hear from the specialist today. Then I'll take him in and get the ultrasound, and whatever other imaging needs to be done, which will be much better diagnostic tools because it will give a very dynamic view of the heart and surrounding organs, mapping their actual function and lack of, rather than a static still-life radiograph.
My dogs, Jazz and Tango in better days (2015) Both are rescues, both pretty much at death's door when I got them.
