A cheeky 2:
Desensitisation to leads
mine had her lead clipped on and off alot without going on walks. She got used to just "being" with it on.
we learnt from our old dog who got super hyped everytime the lead came out
We can now pop her on the lead for example in others houses when shes struggling to settle. When we have dog visitors to the house, human visitors, drop something dangerous or just when we need her to settle. She had an injury at one point and it saved her from complete crate rest, and it also makes it far easier to get out the door.
2)Practice being bored, teaching calm and start as you mean to go on
There's some much information on enrichment that it's tempting to over do it. Half the time when they are naughty they are over tired. It's like a toddler running around manically at bed time. If they have 6 walks a day and 3 kongs a day then they will expect that every day. It's really easy to accidently create a dog that can't settle and is on the go 24/7 because they don't learn to just be. If they walk 2 miles a day, then you'll need to walk them 2 miles when it's raining and you're ill. Ocassional low stimulation, no walk days often does wonders to bring puppies down
Learning to just sit on a park bench and watch the world go by is far better training then manically bombing around with a group of dogs. If you want to one day have a picnic in the park they will have to practice just sitting in those kind of environments
