Hi just a quick question. We get our puppy next week (can't wait) when she is 8 weeks old. She will have had her first vaccination by then, but my question is regarding puppy parties and puppy training classes - do I have to wait until 7 days after her second vaccination to attend these? I am aware that the socialistion window closes at 16 weeks, but if she is not allowed in contact with other dogs until 13 weeks that doesn't leave much time. The trainer that I have been in contact with says he can take puppies as long as they have had their first vaccination. Isn't this risky? Sorry to be a pain. This is my first dog as an adult and I am like an expectant father... clueless and nervous.
