Do Dogs Lose Baby Teeth? Everything About Puppy Teething
Finding a tiny tooth on the floor or discovering your puppy is extra mouthy can prompt a flurry of questions. Do dogs lose baby teeth? Absolutely — and understanding this natural process helps you support your puppy through it. The question of do dogs have baby teeth that fall out surprises some first-time dog owners who didn’t realize puppies have a full set of deciduous (baby) teeth. If your dogs tooth fell out unexpectedly, it’s most likely a normal part of the teething process rather than cause for alarm. If my dog lost a tooth and is an adult dog, however, that’s a different situation requiring veterinary attention. Understanding the full timeline of dogs teething prepares you for one of puppyhood’s most intensive phases.
Puppy Teeth: The Complete Timeline
Baby Teeth Erupt First
Puppies are born toothless and develop their first deciduous teeth (28 baby teeth) starting at around 3–4 weeks of age. These sharp little “needle teeth” are fully in place by about 8 weeks — right around the time most puppies go to their new homes. The answer to do dogs have baby teeth that fall out? Yes — all 28 of them make way for 42 adult teeth.
When Teething Begins
The dogs teething process — when deciduous teeth loosen and fall out to make room for adult teeth — typically begins around 12–16 weeks of age and continues through 6–7 months. The incisors fall out first, followed by the canines and premolars. Many owners never find the actual teeth because puppies often swallow them or they fall out during eating.
Signs of Active Teething
During active teething, puppies chew everything in sight to relieve gum discomfort. You may notice increased drooling, minor bleeding from the gums, reluctance to eat hard food, and obviously accelerated destructive chewing behavior. Providing appropriate chew toys — frozen rubber toys, cold wet washcloths — helps soothe sore gums without destroying your belongings.
What to Do When a Dog’s Tooth Falls Out
If a dogs tooth fell out and your dog is between 3–7 months old, this is entirely normal. You don’t need to do anything unless the puppy is in obvious distress or there’s significant bleeding that doesn’t stop within a few minutes. Occasionally a baby tooth doesn’t fall out when the adult tooth erupts — this is called a retained deciduous tooth and requires veterinary extraction to prevent the adult tooth from being pushed out of proper alignment.
If my dog lost a tooth and is an adult dog (over 1 year old), dental disease is the most likely cause. Periodontal disease — infection and inflammation of the tissues supporting the teeth — is the leading cause of tooth loss in adult dogs. Adult tooth loss always warrants a veterinary dental examination. Regular dental cleanings under anesthesia (typically annually for most dogs) prevent the gum disease that leads to premature tooth loss.
Supporting Your Puppy Through Teething
Make the dogs teething phase more comfortable and protect your belongings with these strategies: Provide a variety of appropriate chew toys with different textures. Freeze a wet washcloth or KONG toy filled with pumpkin or broth for soothing cold pressure on sore gums. Puppy-proof your home aggressively during this phase — cables, shoes, furniture legs, and children’s toys are all at risk. Supervise play sessions and redirect chewing to appropriate items consistently.
Key takeaways: All puppies lose their 28 baby teeth between 12 weeks and 7 months as 42 adult teeth grow in. This is normal, expected, and manageable with appropriate teething toys and supervision. Adult tooth loss is not normal and always requires veterinary evaluation — early intervention prevents more serious dental disease.
