All dogs will push their boundaries.Mine do.WE were going to cook some steaks on the grill and one of our vizslas decided to grab one of them off the countertop.He got caught right away so he didn't get to eat it but I feel like I had to sell my soul to get him out of trouble with the misses.Always keep the water bottle handy to give them a squirt if the feel a little mischievous.Reinforcement is the key to learning.I guess I will be filling up that bottle of learning.By the way they are fourteen months now and this was the "good dog".
