How old do dogs start to grow their deciduous teeth

About 20 days, most dogs begin to grow teeth, and baby dogs begin to grow deciduous teeth at about 3-6 weeks. Usually between 4 and 6 months of age, a dog’s baby teeth will begin to slowly be replaced by strong permanent teeth. Of course, some dogs may start to change teeth a little earlier or a little later. Some dogs start to change their teeth at 3 months, and some are still changing teeth at 9 months. This varies from dog to dog. Most dogs have permanent teeth when they are 6-8 months old.



1. Dogs should not eat overheated or hard food when they are teething. This will irritate the new teeth and gums, and can easily lead to gastrointestinal problems.
2. During this period, parents should pay more attention to the growth of their dogs’ new teeth. Sometimes a lot of new teeth grow out, but the old teeth cannot fall out. Over time, it is easy to cause the new teeth to become incorrectly positioned or cause Gum problems. If the old teeth still don’t fall out, parents can try to gently shake the dog’s old teeth with their hands to help them fall out, or they can find a pet hospital and ask a doctor to help extract the teeth.
3. When teeth are changing, dogs will have a serious tendency to bite because they feel itchy or uncomfortable. Therefore, parents must pay attention to precautions during this special period. Never underestimate how disruptive it can be for your dog to lose his or her teeth. All items that may become targets for dog bites must be put away to avoid heroic sacrifice. In particular, wires, power supplies, detergents, etc. must be kept away from dogs to avoid causing harm to dogs.
4. During this period, the dog’s teeth will be very lonely, so parents can prepare pet-specific chewing toys in advance, such as dog chews or molar bones, which can divert the dog’s energy well. Move away from furniture and kill two birds with one stone.
