In general, it will not harm a puppy to have vaccinations twice unless it is a vaccine that the animal has a reaction to. Of course, we don't recommend that you get the vaccines off schedule, but most vaccines are tested so that if they are given at a higher than usual dose, it will not be harmful to the animal. Your pet may be more lethargic, painful at the injection site, etc etc, but in terms of serious side effects, you should be OK as long as there are no actual adverse side effects or reactions to the vaccine itself.

Your pet should be fine. Double vaccination does not cause any harm in most cases and you should just watch out for the normal vaccine reaction symptoms that can be cause by just one vaccination which include: vomiting, diarrhea, lack of appetite, facial swelling and lethargy. If you do see these symptoms then call your vet for standard vaccine allergy treatment. However Stat should be fine if she had these vaccines before with no issues bc the double vaccination itself won't harm her.

It can be dangerous if Lucky is exposed to unvaccinated dogs or dogs of unknown vaccine status. You should schedule the 2nd and 3rd rounds of vaccines as soon as you can. Keep him indoors or away from unknown/unvaccinated dogs until about 2 weeks after he is fully vaccinated.
