Congratulations on your new puppy! Copper looks like such a sweet pup! Unfortunately, puppies should not be taken outside until they are fully vaccinated. Typically puppies require three sets of shots at least 2 weeks apart, starting at 6-9 weeks. Until Copper is vaccinated, he should not go outside or have contact with other dogs to protect him from viral infections such as distemper, parvo, and rabies. You can begin potty training him to use a wee-wee pad before he can go outside. For his flea prevention, you can use a product that is labeled for puppies, and follow the directions on the box regarding the minimum age (most products are labeled for puppies at least 8 or 12 weeks of age). Good luck with your new puppy!
