I like the dog, but I feel sort of how I felt about my sister's dog when I took care of him for a couple of months while my sister traveled. I enjoyed having him around and we had fun together, but the thought of giving him back to my sister didn't upset me and I wasn't sad after I did. If somehow it turns out that my new dog ran away from a loving family and they found out that I had her, I don't think it would be difficult for me to give her back to them.
