Yep I totally agree! When we first got Billy I thought we had picked the naughtiest puppy ever, biting nipping,chewing. Although I must say I have learnt so so much from COL, you must stay in touch. Its great,instant advice!
Like you we bought Billy from a"dealer", we really had no idea until afterwards why we had done wrong. :oops:
We take Billy to puppy training classes. He started at 14 weeks and goes every week without fail .He is 7 months now and still goes. He has moved out of the puppy class now and has moved upinto intermediate class now and is the youngest dog there. training classes are not only good for your puppy but it is good for you too, we learnt so so much from the people who run the classes, we received bundles of advise etc.
Billy was a real night mare when we first got him, my hands were so sore due to his biting.His teeth were like razors. He did calm down but it took a while. He socialised a lot with other puppies which often involved him biting the other puppies! it looked so painful but that is how they play! I used ot say a firm NO,if that didnt work i would lock himout of the room for a couple of minutes.It will get better it just takes time
