Yes, there can be consequences if you don’t stop your puppy from biting. Here are some potential consequences:

1. Injury: Biting can cause injury to you, your family, other animals, or other people. Puppies have sharp teeth, and even a playful nip can cause bruising or puncture wounds. If your puppy’s biting is not addressed, it can escalate to more serious bites that can cause significant injury.
2. Aggression: If your puppy is not taught to control their biting behavior, it can escalate to more aggressive behavior. This can lead to serious behavioral problems, including aggression towards other animals or people. This can become a safety concern and may require professional intervention to address.
3. Socialization problems: Puppies that are not taught to control their biting behavior may have difficulty socializing with other animals or people. This can lead to isolation, fear, and anxiety, which can affect their overall well-being.
4. Legal issues: If your puppy bites someone and causes injury, you could be held liable for the damages. This can include medical bills, legal fees, and even the cost of putting your dog down.
5. Difficulty training: Puppies that are allowed to bite may have difficulty learning other commands and behaviors. This can make training more difficult, and can lead to other behavioral issues that are more difficult to address.

In conclusion, there can be serious consequences if you don’t stop your puppy from biting. Injury, aggression, socialization problems, legal issues, and difficulty training are all potential consequences of allowing your puppy to continue biting. It’s important to address biting behavior early on to prevent these issues from developing. With patience, consistency, and proper training, you can teach your puppy to control their biting behavior and become a well-behaved companion.
