Health & Development Notes for Shih Tzu Puppies
Let's talk about: Narrow Nostrils & Teething
It is not uncommon for young Shih Tzu puppies to appear to have narrow nostrils during periods of growth and teething. Some puppies may snort, make additional breathing noises, or develop a small amount of clear nasal discharge during this stage.
Because the head and facial structures continue to mature throughout puppyhood, veterinarians will often recommend monitoring these puppies over time before making any decisions regarding treatment. In many cases, breathing improves as growth continues and teething is completed.
For this reason, puppies with narrow nostrils are frequently reevaluated later in development to determine whether the appearance and function of the nostrils have changed with maturity.
As always, puppies should remain active, playful, comfortable, and able to eat and exercise normally. Any puppy showing significant breathing difficulty or other concerning symptoms should be evaluated by a veterinarian.
Teething Changes
Teething can bring a variety of temporary changes, including increased chewing, drooling, mild gum irritation, and occasional nasal congestion. These symptoms are usually short-lived and resolve as the adult teeth erupt.
Most puppies continue to thrive throughout this stage and require nothing more than routine observation and supportive care.
