How to tell the age of a Teddy dog

The common method to determine the age of a dog is through observing their teeth. Here are the signs of each stage:

  • Only sharp, fine milk teeth: Less than 2 months old.
  • Starting to replace milk incisors: 2 to 4 months old.
  • Replacing canine teeth: 4 to 6 months old.
  • Replacing molars: 6 to 10 months old.
  • All teeth grown fully, bright and white: Around 1 year old.
  • Lower incisor tip worn down: Around 2 years old.
  • Upper incisor tip worn down: Around 3 years old.
  • Both upper and lower incisors worn down and turning yellow: 4 to 5 years old.

The teeth condition differs between different ages of Teddy dogs.

Judgment criteria:

  1. Teeth grow irregularly and unevenly at around 20 days.
  2. At 30-40 days, milk incisors grow in fully.
  3. At 2 months, all milk teeth grow in, sharp and tender white.
  4. At 2-4 months, the first milk incisors are replaced.
  5. At 5-6 months, the second and third milk incisors and all milk canine teeth are replaced.
  6. Above 8 months, all teeth have been replaced by permanent teeth.
  7. At 1 year, permanent teeth grow fully, bright, and firm, with a sharp tip on the upper incisors.
  8. At 1.5 years, the tip of the lower incisor is worn down.
  9. At 2.5 years, the tip of the second lower incisor is worn down.
  10. At 3.5 years, the tip of the upper incisor is worn down.
  11. At 4.5 years, the tip of the second upper incisor is worn down.
  12. At 5 years, the tip of the third lower incisor is slightly worn, and the first and second lower incisors are worn into a rectangle.
  13. At 6 years, the tip of the third lower incisor is worn down, and the canine teeth are dull and rounded.
  14. At 7 years, the first lower incisor is worn to the root, with a longitudinal elliptical wear surface.
  15. At 8 years, the first lower incisor is worn forward.
  16. At 10 years, the second lower incisor and the first upper incisor have a longitudinal elliptical wear surface.
  17. At 16 years, the incisors fall out, and the canine teeth are incomplete.
