the principle purpose to keep away from this is because small toy breeds just like the yorkie are predisposed to the circumstance of collapsed trachea. the trachea (windpipe) is surrounded with the aid of rings of cartilage. one or extra of the rings can weaken over time, ultimately collapsing inward. when this takes place, it could be especially painful and critically intrude with breathing. symptoms include trouble ingesting and a honking-like cough. treatment is lengthy (anti-inflammatories, cough medicine, immediate discontinuation of a collar) and many dogs never fully get better. surgery is an alternative but it's far a totally tricky operation with many risks.
