How long does it take for a Teddy dog ​​to be in estrus?

Teddy female dogs will start to be in estrus at 6-10 months depending on their physical constitution, while Teddy male dogs usually go into estrus after one year old. Female dogs usually go into estrus twice, from March to May in spring and from September to November in autumn. Each estrus lasts for 6-14 days, and a few can go into estrus for up to 21 days. There is no fixed time and cycle for male dogs to be in estrus. The mating of male Teddy dogs and female dogs is generally determined based on the female dog’s estrus period.
