I am not a vet or a trainer, and I will admit that I am not a big fan of vaccines for dogs after the research I have done, but I think two rounds of shots are enough protection imo.
If you trust your trainer I would go with what she advises. If you research the vaccines on the internet they are not really protecting against much anyway and I read that they are not even susceptible to Parvo after 8 weeks, so I would do the reading and research yourself on the value of that third round of shots and then you can make an educated personal decision. You are obviously weighing the risk of an illess with his need to gain th necessary socialization and training needed for his life as your companion. |
