I currently own a 6 year old mutt who I love to pieces and I previously owned 2 shelties and had them both for 3 years since they were puppies.They were rather tough to train so I have experience dealing with stubborn pups. I have done a little bit of pet sitting as well over the years with up to 5 dogs in the house. As an animal lover (especially to dogs) I believe that will make me a good dog sitter and walker. And as long as I am provided the information I need for the dogs I will do the very best I can to make sure your dog is happy! I have also owned several guinea pigs over the years as well.
