How old does it take for a dog to lose its teeth?

The age at which a dog loses its teeth depends on its breed and size. Generally, the deciduous teeth of small dogs begin to grow at 3-4 weeks after birth, and are replaced by permanent teeth at 6-8 weeks; while for large dogs, deciduous teeth begin to grow at 5-6 weeks after birth, and are replaced by permanent teeth at 12-16 weeks. . Therefore, generally speaking, dogs will start to lose teeth around 3 months to 7 months after birth. But the specific situation depends on the dog’s condition. Some dogs will lose their teeth slightly earlier or later. If you're concerned about whether it's normal for your dog to lose teeth, talk to your veterinarian.
