Dexter is now 12 weeks old and requires some a lot of training. He seems very strong minded and driven doesn't listen , but is gorgeous and cuddly in between nips 
Anyhow, my question is what would be best - an ABDT trainer who offers puppy classes or the KC staged training programmes, starting with Foundation Puppy or an independent ? Or is it a non question as it will of course vary and depend on the trainers?
He is a Bedlington Terrier.
Thanks
