I have owned small (Miniature Pinscher) to large dogs (Rhodesian Ridgeback). I have walked all kinds of dogs with multiple repeat customers. I walk dogs for exercise, side income, and because I understand and get along with dogs. I just had a dog walk job where the owner could not get the dog to stop biting the leash so I gave it something else to pick up. I held a stick in my hand and off we went with no leash biting. I told the owner about this so together we may be able to stop the leash biting. I am caring for my older dog at home now and walking for repeat customers so I may not be available all the time, sorry. Thanks for looking.
