How to calculate the age of a golden retriever? Determine the age of a golden retriever based on the teeth: the deciduous teeth of a golden retriever puppy will grow in about 2 months after birth, and all the deciduous teeth will be replaced by permanent teeth after 8 months; the first, second, and third teeth of the upper and lower jaws of dogs aged 2-5 years The peaks of the three incisors gradually disappear; the upper and lower incisors of golden retrievers aged 6-10 years gradually grind into oval shapes, and the canine teeth begin to fall out after the age of 10.

Puppies will grow their deciduous teeth around 20 days after they are born. At 4 to 6 weeks old, their deciduous incisors will all grow.

At 2 months old, all 28 deciduous teeth have appeared. At 2 to 4 months of age, the first deciduous incisor is replaced.

At 5 to 6 months of age, the 2nd to 3rd deciduous incisors and deciduous canines are replaced.

After 8 months of age, all teeth are replaced with permanent teeth.

In a 3-and-a-half-year-old dog, the peak of the first incisor of the upper jaw was lost.

In a 4 and a half year old dog, the peak of the second incisor on the upper jaw was lost.

In a 5-year-old dog, the peak of the third incisor of the mandible is slightly obliterated, while the first and second incisors of the mandible are ground into a rectangular surface.

In a 6-year-old dog, the peak of the third incisor of the mandible has been worn away, and the canine teeth have been ground into a blunt round shape.

In a 7-year-old dog, the third incisor tooth of the mandible is worn to the root of the tooth, and the wear surface is vertically oval.

In an 8-year-old dog, the first incisor of the mandible is worn and tilted forward.
