The need to determine the age usually arises if the animal comes to you by accident. In order to understand how old your dog is, you need to pay attention to the condition of the teeth, eyes and hair of the animal.
Instructions
Step 1
Dogs develop most intensively in the first two years of life. After this period, it is generally accepted that one calendar year is equated in small dogs to five years of life, in medium-sized dogs to six, and in large breeds to seven years.
Step 2
The easiest way to start determining age is by examining your teeth. If you have a puppy, then you should know that the incisors and canines in the upper jaw begin to erupt at 20-25 days of life. By the month, the baby should have a full set of milk teeth. Then the milk incisors begin to change at the age of 4-5 months, the canines erupt at 5-6 months. By the time the dog is one year old, the entire milk line should have changed. By the age of one and a half years, the toes of the lower jaw begin to gradually wear off. By the age of 2, 5 years, the middle incisors of the lower jaw are worn. Teeth begin to lose their shine and whiteness. At the age of three, the toes of the upper jaw begin to wear off. At the age of four, the middle incisors of the upper jaw are erased. At the age of five, the canines are also erased. On examination, they look dull. From the age of six, the dog's teeth begin to turn yellow, tartar appears. At an older age, tooth loss is possible. It should be borne in mind that the condition of the dog's oral cavity largely depends on the conditions of its life. Therefore, if you doubt the correctness of your calculations, consult your veterinarian.
Step 3
Also, the age of the dog will help determine the condition of the coat. With age, the coat of dogs coarsens, loses its shine. At the age of six to seven, gray hair appears on the lips and chin. Gradually, it spreads to the entire face and forehead of the dog.
Step 4
After 7 years of age, the dog's eyes seem to be more deep-set. There may be an expansion of the pupil, clouding of the eye (due to age-related eye diseases).
Step 5
You should know what the breed is. So, large dogs live, on average, 10-12 years, medium and small 15-18. Some individuals can live up to 20 years.
