Puppies teethe for several months, up to 6 months or longer. Teething is often not a continuous process for puppies during this time. Puppies usually experience teething off and on over this time.Know More
Puppies begin teething around 3 to 5 weeks of age. This is when their final baby teeth are breaking through the gums. They begin losing their baby teeth at about 3 to 4 months old. At this time, the puppy is both losing and growing teeth simultaneously, which leads to the chewing commonly associated with teething. Puppies should finish teething at around 7 months old and have a full set of adult teeth at 8 months old.
