I taught my puppy sit and down. (lay down). He got sit in a few minutes very easy. Down he got pretty easily too he doesnt just lay down he basically throws his front legs out and slams to the floor its quite funny. But he has a new habbit of when i say down. he lays down and starts barking...i think he wants to play. (i tell him down before I throw a toy for him). Should i correct the barking or just let it be?
