Conversion between Dog Age and Human Age
Although the development speed of large dogs and small dogs differs somewhat, generally dogs can grow to the equivalent of an 18-year-old human by one year old. Each additional year after that corresponds to approximately 4-5 human years.
If further divided, it can be categorized as: before 3-4 months is the puppy stage, up to 3 months is a young dog, by 6 months it can be called a small dog, around one and a half years is its youth period, by seven and a half years the dog should be considered as entering adulthood, and beyond this age is the senior stage. Among these, the most important period for a dog is its adolescence, during which it is in the most critical stage of body growth and character formation. Caretakers should pay attention to its food balance, mental care, and training.
Female dogs have two heat periods each year and will only mate during these times.
The heat period of female dogs can start as early as about 6 months of age or as late as one and a half years. The interval between each heat averages six months, occurring twice a year. During heat, the female dog's tail area swells, and continuous bleeding lasts for more than 10 days. Generally, mating only occurs on the 10th to 12th day after bleeding starts; these days are called the mating period. Outside of the heat period, female dogs show no interest in male dogs.
Unlike female dogs, male dogs do not have a specific heat period and can mate at any time during the year.
