Most baby teeth are all gone by five months, and all adult teeth will be visible between eight to twelve months.
They may also start acting restless or whining due to their teeth. They will also spend a lot of time sleeping in between playing and chewing.
At this age, the puppy may ignore you and forget behaviors they previously learned.
Whenever you first get a puppy, you should take them to the vet to get a checkup. The vet can tell you their age during your first visit.
