when do puppies lose their teeth

Puppies typically start losing their baby teeth around 3 to 4 months of age. This teething phase generally continues until they are about 6 to 8 months old, by which time all their baby teeth have been replaced by permanent adult teeth. The first teeth to fall out are usually the incisors, followed by canines, then premolars, and finally molars, with adult teeth erupting in roughly the same order. By about 6 to 7 months, most puppies have their full set of adult teeth, totaling 42 in number. During this time, puppies may chew more due to teething discomfort, and it's normal for baby teeth to be swallowed or found around the house.
