The ovulation period of puppies is about 10 days, and the specific time depends on factors such as the size, age and gender of the puppy. During the ovulation period in puppies, they usually lose appetite, increase sexual desire, and their body temperature rises and their bodies become moist. These symptoms usually indicate that the puppy is entering pregnancy or breeding.

However, while a puppy's ovulation period is very important to pet owners, pet owners should not affect their puppy's health by over-exciting or stimulating them. In addition, if pet owners want to provide nutrition to their puppies, then they should provide their puppies with appropriate food and ensure that their puppies are in good health.

To summarize, puppy ovulation is very important to pet owners, but pet owners should ensure the health and happiness of their puppies through proper care and protection.
