I figured at 4 months he would have just had his 2nd shot. They're pretty safe after the 3rd booster. I'm just used to my vets who don't do the third one until about 4 and a half months or even later sometimes. Finn might be on a different schedule though.

Its a good idea to clarify with your vet. I didn't mean to worry you or anything. I'm just used to counseling people at the shelter who adopt 8 week old puppies and plan on taking them to Petsmart and dog parks at that age I'm sure Finn will be fine though since he'll be done with shots!
