Pet Sitter in Saint John, New Brunswick

I am interested in walking medium or small dogs. I like puppies too. I have an elder cat who is very possessive of me so I'm unable to get my own dog at this time. I'd like to walk nice friendly dogs not any aggressive or reactive dogs. I owned good natured labs but now I'd like to walk smaller dogs or puppies. I will dogsit but not at my own house due to my cat. I will clean up an occasional mess in the house and pick up during a walk. Will not clean up owners outside property. My dogs were crate trained so I'm familiar with how that works and how it is used in housebreaking. I am kind to dogs and do not like harsh training methods. I'm not a professional trainer but will help in training with basic things like sit, NO, come. This would be with puppies.
