How to judge the age of a Papillon Dog? The size of a Papillon Dog is mainly judged based on the growth status of the teeth, the tooth peak and tooth wear degree, the shape and color, etc. Teeth begin to appear around 20 days old, and the primary incisors are fully formed at 4 to 6 weeks old. The deciduous teeth begin to be replaced at the age of 2 to 4 months. From the age of 8 months, all the permanent teeth are replaced. The permanent teeth grow in length at the age of 1. The peaks of the teeth begin to disappear at the age of 1.5 years.
In order to make it easier to grasp, the methods for determining the age of a dog are introduced as follows:
20 days to start teething.
4 to 6 weeks old: The deciduous incisors are all in length. When the baby is almost 2 months old, all the deciduous teeth are fully elongated, white, thin and pointed.
2 to 4 months old: Replace the first deciduous incisor.
5 to 6 months old: Replace the second and third deciduous incisors and deciduous canines.
Since 8 months of age: All teeth have been replaced with permanent teeth.
1 year old: The permanent teeth are all long and bright, with sharp protrusions on the incisors.
1.5 years old: The canine peak of the mandibular first incisor wears to the level of the small peak. This situation is called the peak disappearing.
2.5 years old: The peak of the second mandibular incisor disappears.
3.5 years old: The peak of the maxillary first incisor disappears.
4.5 years old: The peak of the maxillary second incisor disappears.
5 years old: The peak of the third mandibular incisor is slightly worn, and the wear surfaces of the first and two mandibular incisors are rectangular.
6 years old: The peak of the third mandibular incisor disappears and the canine teeth are blunt and rounded.
7 years old: The mandibular first incisor is worn to the root of the tooth, and the wear surface is vertically oval
8 years old: The first incisor of the mandible is worn and tilted toward the front.
10 years old: The wear surfaces of the second mandibular and maxillary first incisors are longitudinally oval.
16 years old: The incisors are lost and the canines are incomplete.
