My pup is 5 months old and from DDR/Czech lines. He's a good guy. He is typical of his lines in the sense that he is slower to mature than my 3 year old female ever was (different lines though too). We just recently graduated from our first obedience class together. He was the youngest in the class. He's really good with kids, one thing I consider a must in any dog, as I have a 4 and 5 year old. Even if he turns out to be very aloof with outsiders (which for me is a big desire honestly), I want him absolutely 100% perfect with kids. He likes them so we're good. He just needs to learn that no jumping means absolutely no jumping.
I just posted a thread earlier.... take a look. He's playing tug with my 5 year old.
How to wear out your 5 month old puppy (pic heavy)
They tend to be what you put into them. They're challenging and fun and exasperating and more fun. I love my guy. Wouldn't trade him for anything and I'm really excited to see him grow and become the great dog I know he'll be.
The more people I meet and talk to,the more I love my dogs and their intelligence.
