I have had a German Shepard for all of my childhood who I took care of daily, walking her everyday and taking care of her. In her older years her back legs became paralysed so she had to use a wheelchair, so I have a lot of experience with older dogs who are not in their full mobility. More recently my parents got a Labrador puppy, who is full of energy, and not easy to walk, so I have a lot of experience with younger dogs as well who are not fully trained yet. I also have lived in a household with two cats, so I have experience of taking care of them and even walking a cat on a leash. I do not have a preference for kinds of dogs or cats, I approve of them all.
