I've dog sat a boxer for about a year off and on. The longest I watched her at once was 2 weeks. I love dogs, and almost growing a bond with them. I would take her for walks, I would let her sleep with me. She was my best friend. Of course, she knew who her master was. I do have Cerebral Palsy, but the owner still gave me the chance and didn't limit me, and for that I am forever thankful. I prefer medium dogs, unless they're very well leash trained. Since I'm not the strongest because of my cp, therefore I don't want to watch a large dog and then they see a dog they strongly dislike... and then you know what would happen from there.
