I've had my doodle for 3 years now and it never ceases to amaze me on how quickly they learn what is expected of them. For instance, 3 yrs. ago when we 1st introduced our doodle to our household, we already had a Brittany. We set up 2 sets of feed bowls, one for the new guy and of course, the Brittany already had hers. Well my doodle loves to eat, my Brittany, not so much. The Brittany's food can hang around in her bowl all day and she won't touch it. Well, looks like a perfect double dip situation for my doodle. But no, all it took was that very 1st day at our house when he finished his bowl of food and mosied over to the Brittany's bowl to start his double dipping and our reprimanding him with a stern voice, No, No, Lucky that's K.D's food! This is your bowl! And do you know that to this day, 3 years later, he still has never eaten her food! We can be gone for hours, come back and still it sits! There are more examples but this one impresses me the most because like I said, my doodle loves to eat! What are the behaviors of your doodles that impress you the most?
