[Lucy's mom]

This is all making me so nervous. I just bought a puppy wellness program at my vet that includes 2 complete physicals, 2 distemper vacs, 2 bordetella vacs, 2 lyme vacs, rabies vac, fecal check, one deworming and 10% off of spay. This package is for puppies 12 weeks and older and the vacs are given at 3-4 week intervals. The breeder gave Lucy at 7 wks of age a Univac 7 (which I have no idea what that is) and another Univac 7 at 10 wks of age. I brought Lucy to the vet at age 12 wks (which was last saturday) and she rec'd under this package a DHLPP vac #2, canine lyme disease and bordetella as well as a dewormer. So the reminder sheet for when I bring her in at 3-4 weeks from now states DHLPP vac annual, bordetella vac annual and canine lyme disease annual.
My questions are, how many shots of DHLPP did she have already??? Because my vet receipt from when I brought her in at 12 wks states DHLPP vac #2. So did she have 2 already and in 3-4 wks from now she will get a third one or will that be her 2nd one? If she already had 2, do you think it is safe for her third one (if they get 3) if she hasn't had a reaction so far?? Am I making sense? HELP!!! I feel so bad for Romeo and his family and am scared to go through the same experience!
