The Golden Retriever is a popular dog breed loved for its docile temperament and smart brain. Many Golden Retriever owners or potential owners want to know how to tell the age of a Golden Retriever, whether to adopt an adult dog or to better care for their own pet. This article will introduce in detail the method of judging the age of golden retrievers through teeth, hair, behavior and other aspects.
1. Determining the age of a golden retriever through teeth

Teeth are one of the most common ways to determine a dog’s age. The growth and wear of a Golden Retriever’s teeth can more accurately reflect its age. The following are the dental characteristics of golden retrievers at different ages:
| age stage | dental characteristics |
|---|---|
| 2-4 weeks | Baby teeth start to grow in |
| 3-4 months | All deciduous teeth have grown in, a total of 28 teeth |
| 4-6 months | Teeth change begins and deciduous teeth gradually fall out |
| 6-8 months | The permanent teeth are basically all elongated, with a total of 42 teeth. |
| 1-2 years old | White teeth with sharp tips |
| 3-5 years old | The teeth begin to turn yellow and the tips of the teeth are slightly worn |
| 5-10 years old | The teeth are obviously yellowed and the tips of the teeth are severely worn. |
| Over 10 years old | The teeth are loose or missing, and the wear is very serious |
2. Determine the age of golden retrievers through their hair
The hair changes of golden retrievers are also an important indicator of age. As you age, your golden retriever's hair will change in texture and color.
| age stage | hair characteristics |
|---|---|
| Puppy stage (0-1 years old) | The hair is soft, fluffy and light in color |
| Adolescence (1-3 years old) | Hair becomes thicker and shiny |
| Adulthood (3-7 years old) | The hair is the most abundant and the colors are the brightest |
| Middle age (7-10 years old) | Gray hair begins to appear, especially around the mouth and nose |
| Old age (over 10 years old) | Increased gray hair and thinning hair |
3. Determine the age of golden retrievers through behavior
The behavior pattern of golden retrievers also changes with age, and observing their daily behavior can help determine their age.
| age stage | behavioral characteristics |
|---|---|
| Puppy stage (0-1 years old) | Lively and active, curious, likes to bite things |
| Adolescence (1-3 years old) | Energetic, strong learning ability, may have a rebellious period |
| Adulthood (3-7 years old) | Stable character, well-trained, and highly obedient |
| Middle age (7-10 years old) | Less activity, more calm |
| Old age (over 10 years old) | Increased sleep time and decreased activity ability |
4. Determine the age of golden retrievers through the eyes
Golden Retriever’s eyes also change with age, and older Golden Retrievers may show some eye characteristics.
| age stage | eye characteristics |
|---|---|
| puppy stage | Eyes clear and bright, full of curiosity |
| adulthood | Steady eyes, clear irises |
| old age | The eyes may have cloudiness or cataracts |
5. Precautions for comprehensively judging the age of golden retrievers
1. Using any method alone may not be accurate enough. It is recommended to make a judgment based on multiple characteristics such as teeth, hair, and behavior.
2. The development speed of different golden retriever individuals may be different, and factors such as living environment and diet may also affect appearance characteristics.
3. If you are adopting or purchasing an adult golden retriever, it is recommended to ask for veterinary records, which are the most accurate proof of age.
4. Take your golden retriever for regular physical examinations. Veterinarians can more accurately assess their actual age through professional examinations.
5. Elderly golden retrievers require special care and timely adjustments to their diet and exercise plans to adapt to their age changes.
Through the above methods, you can more accurately determine the age stage of your golden retriever and provide more appropriate care. Remember, regardless of age, Golden Retrievers require love and attentive care from their owners.
