Miko is now four to five month old. She had lost her forth teeth. I heard from a friend when puppy had all their full set of teeth replace, their size will be fully structured. I am quite excited to see all her teeth replace. Although she had gained some weight but she is still small. Hopefully she can remain in this cute little ball-size.

During puppy hood, dogs grow 28 puppy teeth. These teeth arrive between their sixth and eighth week of life. Puppy teeth fall out and larger adult teeth replace them. This process is extremely uncomfortable for the puppy. During this time, puppies chew everything they can to push the teeth through the gums quickly. Keep your pet from damaging furniture and personal belongings by providing plenty of durable chew toys.It is common for puppies to swallow their teeth. Consult a veterinarian if the puppy tooth does not completely fall out. Some teeth catch between adult teeth. A veterinarian will safely remove the baby tooth.
Between the ages of three months and seven months, a puppy begins to lose its deciduous teeth. Each deciduous tooth root will generally be absorbed by the adult tooth, though there are instances where this does not properly occur. At three months, the incisors begin to fall out to make room for the new adult teeth.
At the age of four months, the adult molars and adult canines are beginning to come in. Between the ages of six and seven months, the adult molars will come in. Finally, by seven to eight months, the full set of adult teeth should have come in.
By the time a puppy is eight months old, it should have a full set of a total of 42 teeth, but some breeds have more or fewer. The larger the dog, generally speaking, the faster the teeth will appear.
