* Individual Dog Personality: Some dogs are more protective than others.
* Number of Puppies: Larger litters might require more protection for a longer period.
* Other Dogs' Temperament: The presence of friendly, submissive dogs might shorten the protective period.
* Environment: A secure, familiar environment might allow for more relaxed protection.
Important Note: It's crucial to remember that:
* Introducing other dogs too soon can be dangerous. The mother dog may become aggressive even to familiar dogs, defending her pups.
* Socialization of the puppies: After 6-8 weeks, it's important to gradually expose them to other dogs, starting with friendly, vaccinated dogs.
If you have concerns about your dog's behavior towards other dogs or her puppies, consult a veterinarian or professional dog trainer. They can provide personalized advice based on your specific situation.
