Puppies are very susceptible to disease and if a virus is introduced, an entire litter may be lost and future litters endangered. Visitors may have been visiting animal shelters, or other kennels prior to coming to Grothaus, and could transmit viruses quite easily. Some mothers of the pups get very protective at this point, and will get nervous knowing that there are strangers near her puppies. It’s also very difficult to evaluate puppies at an early age, so the best time to come, look at the puppies, and pick up your puppy is after they are at least 7-8 weeks old. At this age they have received their initial vaccinations and their personalities and structure can be evaluated much easier. I understand this is an exciting time and it can be difficult to wait, I’ve been there, and that’s why I will post plenty of puppy photos and videos on our social media accounts and websites.
