Yes, dogs do lose their baby teeth. Puppies are born without teeth and start to get their baby teeth around three weeks old. They usually have 28 baby teeth which begin to fall out around 12 weeks of age. The teething phase, when baby teeth fall out and are replaced by permanent adult teeth, typically occurs from about 4 to 6 months old, with most puppies having lost all their baby teeth by six months of age. The first baby teeth to fall out are usually the incisors, followed by the canine teeth, and then the premolars. Dogs do not have baby molars. If baby teeth (called deciduous teeth) do not fall out when they are supposed to, it can cause dental problems such as overcrowding, bite defects, and increased risk of gum disease. In such cases, a veterinarian may need to remove the persistent baby teeth. Puppies may sometimes swallow their baby teeth, and this is generally not a cause for concern. During teething, puppies may drool more, chew more, and sometimes have minor bleeding when a tooth falls out. In summary:

• Puppy baby teeth emerge around 3 weeks.
• Puppies start losing baby teeth at about 12 weeks.
• Baby teeth are usually replaced by permanent teeth by 6 months.
• Persistent baby teeth may require vet intervention.
• Teething can cause minor symptoms like drooling and chewing.

This is a normal and natural process for dogs.
