I love it when even an eight year old little girl can run a pack of dogs with collective weight of about 900 to 1000 ponds!! She weighs about 60 pounds, just goes to show with a balanced pack of dogs any one can control a yard! I am so so proud of the pack I have built over the years after all the hard work, this is the reward! Please notice that the little girl in my yard is calm, and firm and is getting the results she is looking for and that the dogs are respecting her authority!! Way to go Ray! Proud of you, and you have a future job with me anytime you want it! P.S not all the dogs in the yard belong to me by the way some are in for day care, but I have trained since they were puppies!
