When out for a walk, my little dog (18 mths) will often sit down, let me continue walking until I turn around to say 'come'. She will then run to me and get her treat. I think she thinks she has trained me to do this! I also wonder if she just keeps picking up things in her mouth so I will say 'drop' and she will get a treat. Is this just my dog or has anyone else's dog got the better of them? Should I fade out the rewards? When she was younger and I took her to puppy school, the trainer said that training should be done throughout the dog's life, a little bit every day, but I think she is getting crafty now!
