At around 12 weeks, the deciduous teeth begin to fall out, and the permanent teeth begin to erupt. Normally by 6 months of age, all permanent teeth have erupted, and all deciduous teeth have fallen out.

Which puppy teeth fall out first?

The first to be lost are the incisors, the front six teeth on the top and bottom. Next, the long fang-like canine teeth should fall out as the permanent canines erupt. All of the 42 permanent teeth should be in place by the time a puppy is about 6 months old.

How do you know when your puppy's teeth are falling out?

When teething occurs, you might notice the puppy drooling or see little spots of blood on his toys, although if you notice anything unusual, talk to your veterinarian since both symptoms could also be related to a more serious issue. Once your puppy is 6-months-old, his baby teeth should have fallen out.
