Tibetan Mastiffs (certain introduction)
Tibetan Mastiffs are the most sincere and fierce dogs in the world. At the same time, the spirituality of Tibetan Mastiffs also arouses the interest of many people, hoping to find out more. However, they are deterred by the "notorious" reputation of Tibetan Mastiffs and are narrow-minded. We all know that the age of a dog can be judged by examining its teeth, but for fierce dogs like Tibetan Mastiffs, if there is no complete control, the editor recommends not to pay too much attention to their age. If it is a very close owner, or a Tibetan mastiff under anesthesia, then you might as well take a closer look.
Under normal circumstances, the permanent teeth of adult mastiffs are scattered: 6 incisors on the left and right, 2 on the left and right in canine age, 8 premolars on the left and right, 4 molars on the upper jaw and 6 on the lower jaw, a total of 42 teeth. The number of deciduous teeth of young mastiffs is scattered: 6 incisors on the left and 2 on the left, 2 on the left and right of canine, 6 premolars on the left and 6 in total, 28 in total. The age of an adult mastiff is most obvious in the growth, wear, and sharpness of the teeth. The age of a young mastiff can be inferred from the number, strength, age, brightness, etc. of the teeth.
The following are the standards for estimating the age of Tibetan Mastiffs. Due to individual differences, not all Tibetan Mastiffs are the same. Owners may wish to make a rough estimate based on this standard.
After 20 days, the teeth will gradually grow in unevenly. In 30-40 days, the deciduous incisors will all grow in length. At 2 months, all the deciduous teeth are fully elongated, pointed and tender white. 2-4 months, replace the first deciduous incisor. 5-6 months, replace the second and third deciduous incisors and all deciduous canines. Over 8 months, all teeth are replaced by permanent teeth.
1 year old, the permanent teeth are all long, bright and tough, with sharp protrusions on the upper part of the incisors. At 1.5 years old, the peak of the first mandibular incisor disappeared. At 2.5 years old, the peak of the second mandibular incisor disappeared. At 3.5 years old, the peak of the maxillary first incisor disappeared. At 4.5 years old, the peak of the second maxillary incisor disappeared.
At the age of 5, the peak of the third mandibular incisor was slightly worn, and at the same time, the first and second mandibular incisors were ground into a rectangular shape. At 6 years old, the peak of the third mandibular incisor disappeared and the canine teeth were blunt and rounded. At the age of 7, the mandibular first incisor was worn to the root of the tooth, and the wear surface was vertically oval. At the age of 8, the first incisor of the mandible was worn and tilted to the front line.
At 10 years old, the wear surfaces of the second mandibular and maxillary first incisors were longitudinally oval in shape. At the age of 16, the front teeth were lost and the canines were incomplete. 20 years old, canine tooth loss.
