Too many dogs (even among champions) have a gait which does not correspond to the correct gait of the Lhassa.
Like American Cockers do, they the back legs raise too High, showing their pads.
The correct gait of the Lhassa is hopping. It trots light.
This difference is not a small détail but a very serious defect because it result from a lack of angulation and thus from a bad morphology of the dog.
According to Dr. Lescure’s thesis (1960), realized scientifically using radiographies and carried out on Annapurna subjects of Miss Dupont’s, (close to the dogs of origin), the scapulo-huméral angle in the Lhassa is 115°.
The more the scapulo-huméral angle will be open (115°), the more the neck will seem short and the tibio-tarsal angle will be open (150°). That will give the dog a good balance and a light gait (propulsion and traction), trotting «menu» as on air cushions. Back legs pads are hardly seen. Its gait is correct.
On the other hand, the more the scapulo-huméral angle will be closed (90°), the more the neck will seem long, (the first dorsal vertebrae appearing with the cervical vertebrae) and the tibio-tarsal angle will be closed (110° approximately). This accentuated angulation gives the dog a contrained propulsion forcing it to raise its back legs exaggeratedly. Its gait is incorrect.
Whatever the breed, the dog has always seven cervical vertebrae, thirteen dorsal vertebrae and seven lumbar vertebrae.
