I thought I'd hop on here and start sharing things that have worked really well for my dog and others dogs. We know they work for a few reasons. Lets first talk explain what ditching the bowl and routine are and look like.
Ditching the routine works because dogs are AMAZING predictors. They are efficient animals so they quickly work out that keys = leaving, those clothes = keys = leaving. etc. They get themselves into a different energy state before you've even done what you were going to do! Reducing the predictability means there is no point in getting to a different energy state because who knows what were going to do. They place less importance on our movement which is great skill to have when living day to day.
Now obviously they wont apply to every situation or dog. You have to assess your own dog, your own situation before you know if these will work in your life. Some dogs medically can't ditch the bowl for example. Ask a professional as well!
