As is the case with humans, pug puppies are initially born without any teeth. So, they’ll typically grow their first baby teeth within the first 2-3 months. Up until 9 months, teething takes place, whereby the baby teeth fall out and are replaced by adult teeth. During this teething phase, the gums and teeth of a pug will often become sensitive and itchy. To help with this, bones and chew toys are popular choices. Adult pugs shouldn’t lose any of their teeth, so if this happens, it could be a sign of a deeper underlying dental issue which you’ll need to get examined by your veterinarian.
