I deal intensively with dogs for one year. Previously that was only my hobby.I consider it very important that the dog's pack leader accept.I don't discipline their behaviour but I correcting that if it must.Depending on the variety of different exercise needs. I think that based on the description does not turn out how he treats someone with a dog. You need to see the dog's owner well.The dog's demeanour instantly reveals all.If granted a relaxed state of mind is , if it is frustrated or when sinning.
