i can not believe how good the water bottle is working today.. this has been the best day w/ him since the 3rd day i got him. it only took 3 times and he now knows "NO", well i think he always knew it but now he listens to it.. he still cried on his walk but i wouldnt give in and after a bit he gave up and walked and had fun, he even jumped into the mud. thank you very much
