How many months does a Border Collie reach adulthood? A Border Collie is considered a dog when it is 10 months old. Generally, the age of a dog is judged based on the condition of its teeth; over 8 months old, all the teeth are replaced by permanent teeth; 1 year old, the permanent teeth are all long, smooth and strong, with sharp protrusions on the upper part of the incisors.

A Border Collie is considered a dog when it is 10 months old. You can tell your dog's age by examining his teeth. If the teeth are sharp and have not been replaced, it will be within 5 months. It will be around 5 months before the teeth are replaced. It will take about 6-7 months for the blunt teeth to grow in!

Teeth wear (the incisors and front teeth are about 2 to 3 years old), and the back teeth are worn about 3 to 5 years old (these are just routine assessments! The specific situation depends on the dog's various conditions) Purebred There is information for evaluation of dogs. After the puppy period (2 and a half months to 3 months), the dog enters the awkward period - the awkward period of about 10 months. This period is also called the rapid growth period! The hair will appear less and the proportions will appear smaller. Relatively slender, after 10 months, it enters the slow growth period and develops until about 1 and a half years old (male dogs become sexually mature around 10 months old, and female dogs are considered sexually mature for the first time in estrus (usually 6-10 months))

Around 1 and a half years old, the shoulder height and body length are stable, and the weight can change.

The peak period of the whole dog's state is 3 years old. The accumulation of little bits and pieces of training in childhood is the performance of the adult dog's physical fitness (diet, feeding, education, etc.). The normal life span of an average dog is about 14 years, for extra large dogs and extra small dogs. Dogs live shorter lives.

Formula:

A dog’s first year = 15 years

The second year of the dog = 10 years

Each year thereafter is equal to 3 years of human age.

Example: The age of a ten-year-old dog should be: 15+10+(3x8)=49
