Beagles are DEFINITELY not stupid! I started JoJo in puppy kindergarten when she was about 3 months old - we just missed the previous class because it started while I was in NY getting her. We only got to go to 3 classes - tho I did take her to the park every day after work so I could work with her alone. After the 3rd class I got very sick and wound up in the hospital for 2 weeks - so no more puppy classes. It took me a good 6 months to recuperate from the surgery and pancreatitis - and get strong enough to do ANYTHING other than the basics for the dogs. JoJo is 4 years old now - and she DOES remember her lessons that she learned in kindergarten. Stupid? NO! Stuborn? Yes!
