I would get to know their walking speed fast paced or easy going. Each dog has it's own personality I would focus on their own special wants, needs and dislikes. Respect, love and lots of attention is what most dogs want and deserve so I would give it to them. I wouldn't let them chase any other animal's even other dogs. Keeping them safe and out of trouble is important as well. So the owner, dog and I can all be happy. Sometimes relaxing is a good idea dogs need rest but sometimes don't realize it. Puppies are my favorite and no breed is too aggressive for me. I will always have the owners wishes as my guide although the dog might not like it.
