I recently read an article in my local paper about this. I think it is a great bonding experience for you and your dog. It can also help to de-stress our dogs at times when we find ourselves stressed and our dogs react to us.
Here are a couple of links: I had no idea that “doga” has been around for about 4-5 years.
Some positions are possible with small breeds as described in the links. But there is a lot you can do with a medium, large or giant breed.
