I grew up with a German Shepard and a sharpei along with several cats and have always loved having pets. Now I have Cassie who requires a lot of attention but is my heart. I have to exercise her a lot so your dog will get plenty of walks and playtime with Cassie. The apartment is also set up with multiple rooms so the pets can be separated if necessary. My hope is that this can be an opportunity for Cassie to spend more time with other pups in the house. She gets bored sometimes and I think this would be healthy for her. I am able to coordinate with you on feeding and exercise schedules if necessary. I understand how important that can be, especially owning a playful pup like Cass.
