Chihuahua: health conditions to watch
Chihuahuas are tiny, bold and long-lived. Their small size brings a few characteristic considerations, most notably the windpipe and, with age, the heart — both very manageable with early awareness.
What to watch in a Chihuahua
A predisposition is a “worth knowing”, not a diagnosis. Most Chihuahuas never develop these — but knowing the early signs means you can act early.
Collapsing Trachea
Learn about Collapsing Trachea →A weak windpipe is common in toy breeds; a honking, goose-like cough (often on excitement or from a tight collar) is the classic sign, so use a harness rather than a collar.

Learn about Mitral Valve Disease →Like many small breeds, Chihuahuas are prone to a leaky heart valve with age; a yearly heart check to catch a murmur early is the key.

Stent or Medication? How to Think About the Tracheal Collapse Decision
The diagnosis is probably already made by the time you reach a page like this. Your small dog has a collapsing windpipe, the honking cough has a name, and someone, a vet, a forum, a worried part of your own head at two in the morning, has used the word stent. Now you're trying to...
Collapsing Trachea Explained: The Goose-Honk Cough
A small dog, often a little older, suddenly produces a cough so dry and harsh it genuinely sounds like a goose honking. It tends to land at the worst moments: when the doorbell goes, when they get over-excited, when they pull on the lead, or after a drink of water. The first time you hear...
Living With a Long-Term Cough: The Honest Long View

What the consult room rarely has time for is the question that comes next, once the dog is snoring beside...
Cough Flare-Up: How to Settle It, and When to Act
There's a difference between the cough you've learned to live with and the one that arrives tonight. The familiar one is dry and honking, a note you recognise and mostly manage. Tonight the bouts are closer together, the sound is harsher, and the smallest thing sets them off. The question that actually matters in that...
Canine Chronic Bronchitis: The Other Long-Term Cough
A small, greying dog who coughs most mornings, after a nap, the moment they get up to greet you at the door. Not a one-off, not a kennel-cough fortnight that came and went, but a cough that's become part of the furniture. If someone has said the words "chronic bronchitis" to you, maybe alongside "we've...
Calming a Chronic Cough at Home: The Daily Things That Genuinely Help
A dog with a collapsing windpipe, or a long-term cough of some other airway kind, usually comes home from the consult with a diagnosis explained and a tablet or two to give. Then the honking cough carries on punctuating the evening anyway, and the obvious question is what else there is to do. That question...
