I have grown up with many dogs, cats, birds, foxes, iguanas, snakes, goats, pigs, flying squirrels.... It goes on. Lots of animals. My chores as a child included caring for the animals. I enjoy it. I love animals and they love me. I have rarely come across a dog that hasn't instantly opened up to me lovingly. I have been walking and sitting for several friends dogs and cats. I have decided to expand as it has been the most enjoyable part of my work days. I take car of my roommates big dog a lot. It's a great dane/ bull mastiff. So big dogs are no problem. Small dogs are great too. Dogs are great all togeather. It's great when you love your job!!!
