go get the bird wrote:Keep him on a check cord. You need to make the distinction that work is work, and when you say here, no matter what, he'd better listen. My dog was on a check almost all the time up until the beginning of this summer (roughly 15 or 16 months old). To this day, she is walked and taken outside with a choke chain and a leash. You need to work on basic OB every time the opportunity presents itself.
Your pup is still young, and you can't expect him to be an expert in every aspect of the game. His failure to listen during basic OB with a bumper means that you've failed him somewhere, or you've yet to teach him what you want. The biggest part is finding out where YOUR shortcomings are and addressing them.
As far as the playing, dropping, and chewing, force fetch will likely take care of those issues, so long as it's done properly. Do some research on FF and CC. Get a training program and follow it. Consult a few pro-trainers and join a retriever club. If you do those things, and dedicate some time to actually learn about training, you will no doubt have a retriever you will be proud to own.
This above , don't FF this pup until after 6 months . His adult teeth should be in . Get someone who knows how to do this , not someone who's done it one time . If you cannot find someone to help , send him to a pro , it will be worth it-trust me ! Good luck and chill out , he's only 5 months . It's all about fun and bonding .
