About 8, 9, 10 weeks. After about 8, 9, 10 weeks of age, or when the puppy arrives at it's new home, the dog should be taught to go potty outside. Do not have paper or potty pads inside your home. Peeing is for outside only, or you are teaching your new pup it is okay to potty inside your home.
A puppy should have its first set of vaccinations at 8 weeks old-most vets will not do the first set before this age because the puppy is too young. The second set of vaccinations is done at 10 weeks (I would advise you also request to have your dog treated for kennel cough and get him microchipped at the same time).
