I tried adding another furbaby but it just didn't work. Tilly was very scared of him. She started hiding and peeing all over herself. It just kept getting worse, so we had to take the puppy back. I would love to have another furbaby but I know that wont be happening. I think most add a dog just fine. I would take her around other dogs and give the other dogs some attention, she how she reacts. Some dogs are just a one dog type, like Tilly, but I think you will be alright.
