Do you know that for dogs, we can judge their age by their teeth, and the teeth of dogs of different ages can be different. Today we will tell you for the dog how to see the teeth age illustration. How do we recognize how old these dogs are from their teeth.
In fact, the age of the dog, mainly to the growth of the dog’s teeth, tooth peaks and tooth wear, shape, color and other comprehensive determination, in order to facilitate the grasp of the dog’s teeth test is introduced as follows:
Adult dogs have a total of 42 teeth and puppies have a total of 28 teeth.
20 days — around the beginning of teething
4-6 weeks of age — milk incisors are complete. Nearly two months of age, all milk teeth are complete, white, thin and pointed.
2-4 months old – first milk incisors replaced.
5-6 months of age – Replacement of the second and third milk incisors and canine teeth.
After 8 months of age – All permanent teeth are replaced.
1 year old – permanent teeth are complete, white and shiny, with cusps on the upper incisors.
1.5 years old – large cusps of the second mandibular incisor are worn down to the level of the small cusps, a phenomenon known as cusp erosion.
2.5 years – mandibular second incisor cusps worn away.
3.5 years – cusp erosion of maxillary first incisors
4.5 years – cusp erosion of the maxillary second incisor
5 years – mandibular third incisor cusp slightly worn, mandibular first and second incisors with spaced wear surfaces.
6 years – mandibular third incisor cusp worn out; canines bluntly rounded.
7 years – mandibular first incisor worn down to the base, wear surface is longitudinally elliptical.
8 years – mandibular first incisor worn down to anterior inclination.
10 years – mandibular second and maxillary first incisors with a longitudinal oval wear surface
10-16 years – incisors are not aligned.
