That's an excellent article, very useful information. We're getting a 8 week old puppy soon, and my question is the following. We've been told that the dog shouldn't meet other dogs and preferably stay at home until he's 12 weeks old, time when the dog will have its second vaccination. During this time we can do some basic training at home, which we plan to do anyway, and this is fine. But dog centers and kennels have what they call "puppy pre-school" classes, specifically designed for dogs between 8 and 14 weeks. So what should we do, keep the dog "isolated" until he's 12 weeks (and had his second vaccination), or taking the dog at 8 weeks old to puppy pre-school classes where he will be in contact with other dogs (all of them having had the first vaccination, of course)? It's confusing for us as newbies. Thanks a lot!
