Today was Lilah's first vet appt and she did great! She was calm and let them hold her and didn't even flinch when getting her nails trimmed. The vet and the vet tech couldn't believe how relaxed she was

(of course she made up for that as soon as she got home and let her crazy puppy side show haha)
I'm trying to come up with a vaccination list and schedule as well as some other meds based on the breeder's recommendations and the vet's (they differ quite a bit). I'll start with saying I'm in the "let's not over vaccinate" group. Anyway, Lilah is due for her 3rd DAPP shot on Saturday (she'll be 15 weeks, 2 days) and the vet wants to give her the nasal bordatella vaccine then as well, but I'm not sure I want to do that. She said that she'd need the bordatella vax if I plan on ever getting her groomed or going to a dog park. (neither are going to happen in the next few months).
The vet also said to do her rabies vax 7-10 days after the DAPP (she'd be 16.5 weeks old) and the breeder says she would try and wait until she is AT LEAST 8 months. My question here is PA state law says I have 4 weeks from the time she turns 12 weeks old to do the rabies vax……so, if I do wait until she is older, am I going to have any problems?
Lastly the vet wants me to put Revolution on Lilah tonight because it's been oddly warm here the last few days and she said there may be ticks (although Lilah is potty pad trained and hasn't even gone outside yet)…..breeder says no way to the Revolution. So I'm on here doing research and asking questions….would love some input. Thanks!
