Do you provide your new parents with a puppy pack of some kind that has the registration papers, health certificates, parents health certificates, and breed information as well as health guarantees and immunization/deworming? Some breeders do not provide this information to the new parents; those are the ones I avoid when purchasing a new puppy. Sorry, got off topic a bit there but here's the recommended schedule. *Remember, I am NOT a VET and this is strictly information that is available at any vet office.
1st shots - NO EARLIER than 6 weeks of age 2nd shots - 9 weeks of age 3rd shots - 12 weeks of age 4th shots - 15 weeks of age 5th shots - 24 weeks or 6 months of age 6th shots - 12 months or 1 year of age Vaccinate annually after the 1st year
Hope this helps give you an idea and best of luck.
Don't worry about tomorrow; it has never happened before.
I get my pups the first series of shots at 6 weeks. I then recommed that the new owners check with their vet regarding when they want them to get their next series. I also give them the same schedule previously provided. Also, eventhough I give my adult dogs all shots except rabis my self, I take the puppies to the vet for theirs. While I am there, I have the vet examine the pups throughly. Doing this gets each puppy a vaccination and health cirtificate issued by my vet, not just my word that "They are healthy." Remember, if in doubt CYA. Make sure that you have done everything possible to insure that you are sending on healthy, happy, well adjusted/bred pups. Anyone can put dog A with bitch B and get puppies, but a good breeder puts time, effort, and soul in to their litters.
If people had emotions as pure as animals, our hearts would have to tripple in size.
I would typically give my pups there first shot at 8wks unless I am going to a show, then they get it at 6wks(I won't show if the pups are younger). I also give the kennel cough at this time. I hand that info over to the new owners, and tell them to give the addtional shots as their vet reccommends. I give my own shots, but each pup see's the vet before it goes to it's new home for a health check.
When I keep a pup, my personal scheduel is 4 shots 4weeks apart, and the one shot at a year. Rabies has to be done at 3months here.
Since you are not a vet, you really can not say how the person should give the shots. If you tell them, and their dog gets sick, it can come back on you. You can advise them of what you do, but don't tell them how to do the shots. Tell them to give shot per the vets instructions.
