What can i do to stop my 17 week old puppy bonnie from pulling on the lead? without using a harness or a halter.She sometimes seems to do it just for the devilment of it and is worse with my wife who walks slower than me i am only taking her for about 20 to 25 minutes 3 times a day. i have started puppy training this week but haven't covered this .any suggestions would be appreciated
She doesn't do it "for devilment" (although I know it feels like it), she does it because she is a puppy and hasn't been taught not too

There are various different methods of teaching a dog not to pull - and I am sure you will cover it in training classes, but not all methods work for all dogs

Don't give up too soon though - consistency is the most important thing; and each time Bonnie pulls she gets a reward (she gets where she wants to go), and so is more likely to do it again - it can take a while
