I not only have 3 fur-babies I personally raised, but have had a number of others previously including cats. All 3 of my dogs know basic commands, without formal training, ranging from sit and lay to go and stay. One can even roll over (at times) upon command! One of my current dogs is a rescue who has grown to love people rather than fear them. My pups range from 1 year to 5 years, also in a variety of sizes. The eldest is the smallest and the youngest is the largest, of course. After raising so many different pets, I have finally decided that I would like to offer my experience to assist in caring for other beloved pets. Also, I bike frequently so walking the roughest of dogs would not be too much of a problem for me to handle.
