The transition to permanent teeth in a pug typically begins around 4 months of age and is usually complete by the time they reach 7 to 8 months old. During this period, the deciduous teeth start to loosen while the permanent ones emerge and push them out. This process is often referred to as "losing teeth" and is a natural part of a pug's development.
In total, a fully developed adult pug has 42 permanent teeth, which includes incisors, canines, premolars, and molars. These permanent teeth are designed to be stronger and more durable than the puppy teeth, enabling the pug to eat and chew properly throughout its life.
However, just like humans, pugs can experience variations in their dental development, including when they lose their puppy teeth. Some individuals may lose their teeth earlier or later compared to the typical age range, and any delays that seem excessive should be discussed with a veterinarian for further evaluation.
