Hi, I have a 12 week old male chocolate lab and my daughter has a 17 week old female chocolate lab. We often spend weekends together at our cabin and get the puppies together at our houses. We supervise their play, but they never seem to tire, which can be exhausting for the adults. I’m looking for some insight on puppies of these ages playing together. How long should we let them go? We do end of separating them from time to time because they will just keep going and going. Thanks for any experience anyone has had with this.
