Determining a Teddy Bear dog's age can be accurately done by examining its teeth. Teddy Bear puppies have 6 incisors on both the upper and lower jaws, 2 canines on each jaw, and 6 premolars on each jaw, totaling 28 teeth. Adult Teddy Bear dogs, on the other hand, possess 6 incisors on each jaw, 2 canines on each jaw, 8 premolars on each jaw, 4 molars on the upper jaw, and 6 molars on the lower jaw, for a total of 42 teeth. A Teddy Bear dog's age can be assessed based on the number of teeth, their condition (new or old), and their level of brightness.
Generally, Teddy Bear dogs have a lifespan of about 12 to 15 years, with very few exceeding 15 years. This is influenced by their living environment, diet, and other factors. If you want to know the exact age of your Teddy Bear dog, examining its teeth is the most accurate method. Below is a detailed guide to help you understand the aging process through dental changes.
Dental Changes at Different Ages
Around 20 days old, a Teddy Bear puppy's teeth will start to emerge unevenly.
At 30-40 days, their milk incisors will have fully erupted.
By 2 months, all milk teeth will be present; they will be sharp, slender, and a milky white color.
Between 2-4 months, the first set of milk incisors will be replaced.
At 5-6 months, the second and third milk incisors, as well as all milk canines, will be replaced.
By 8 months, all of a Teddy Bear dog's permanent teeth will have erupted.
At 1 year, all permanent teeth will be in place; the incisors will have prominent points and be shiny and firm.
By 1.5 years, the points on the first lower incisors will begin to wear down.
At 2.5 years, the points on the second lower incisors will wear down.
By 3.5 years, the points on the first upper incisors will wear down.
At 4.5 years, the points on the second upper incisors will wear down.
At 5 years, the points on the third lower incisors will show slight wear, and the first and second lower incisors will become rectangular.
By 6 years, the points on the third lower incisors will be worn down, and the canines will become blunt and rounded.
At 7 years, the first lower incisors will be worn down to the root, and the wear surface will be elliptical.
By 8 years, the wear on the first lower incisors will begin to slant forward.
At 10 years, the wear surfaces of the second lower and first upper incisors will become elliptical.
By 12 years, the incisors will start to fall out, and the canines may become incomplete.
At 15 years, almost all of the canines will have fallen out.Trusted by:Pet Naming
