I love dogs of all sizes. I do not have children under 12. I have worked with so many rescue dogs and all different types of behavior issues so it is not a problem if your dog jumps or barks or has aggressive tendencies. I have positive methods of dealing with negative behaviors so if you have a bit of a hyper pooch, then I am your person. I understand how important it is for dogs to have loving contact and exercise in order to be healthy and happy. I teach so I am off work and able to give extra time and care during peak vacation seasons. I will happily take pics and videos of your dog while out so you can share in the fun. I personally own a Newfie and a Terrier mix so dog size is seriously not a problem.
