I'm pretty new to puppy ownership and have a collie who likes to herd cars so we are working on giving him other herding outlets and training a strong settle / stay whilst keeping him away from cars so he doesn't get any practicing opportunities. So we're doing a couple of 4/5 minute settles (not on a mat as he'd just hump it) and he has to stay lying down while we do different distractions around him - walking / running in different directions, playing with toys, throwing food etc. He gets fidgety after about 4/5 mins so we end on a high and then we play a one-on-one game like pop bubbles or simple sheepball type of game for aboit 5 minutes. Then he's usually ready for a sleep. Just after a bit of reassurance really that this is the right thing to do. Puppy is 8 months.
