I don't have professional experience but I do have the love for dogs. I myself own a newfie and know how to properly care and love her. She has gotten very big the past two years I've had her, so I am capable of walking caring for large dogs 60+lbs. When I found this site I was so surprised a d excited that their is a job that I would love doing. I am young and have tons of energy. I would even love to take my doggy friends to the dog park less then five miles from me. I take my Newfoundland there and I'm sure they'll love it. I am more than capable to take care of your beloved pups and love them as my own.
