My Newfoundland pup is just gone 3.5 months. Over a week ago he lost a tooth from the thop and now he's lost 2 more from the bottom. Is this normal or is there a prob???

dogs have two sets of teeth just like us, now is about the age that you will start seeing pups milk teeth falling out and probably will do so over the course of the next several months.

Puppies and kittens, like people, have a primary or deciduous dentition. This refers to their baby teeth, which usually are all in place by 6-8 weeks of age and which, by 16-24 weeks, are subsequently replaced by the adult teeth.

But beware of two types of dental problems occurring... traumatic damage to the baby teeth and oral cavity, and improper eruption of the adult teeth. Better visit a vet.
