Hello everyone! I am a brand new shepherd owner and have a few questions/concerns. I received my puppy at 10 weeks old, my breeder had already given him his 1st and 2nd set of shots, as well as, chipped him. When I took him to the vet for a check up as well as his third set of shots, a week after receiving him(11 weeks old), I was told they would have to restart the vaccination process because I did not have the certificates saying he was vaccinated. I contacted the breeder but still have not gotten a reply. When I spoke to the vet, I had him check my puppy for a chip, as the breeder said she chipped him and one was found. I told him about my dilemma with the certificates and etc. He told me not to worry and to bring the puppy back in 2 weeks, they would just give him his 3rd set. My question is what is a normal vaccination schedule? what shots to they receive and at what time? Also, if I where to switch to Dr.Dodd's vaccination, how to I make that switch? How do I properly interpret the schedule? my puppy is 13 weeks now. Sorry about how long this is, I am literally a first time dog owner and have been getting a crash course in a lot of things.
