Hehe. Yes, I can see myself letting a dog or two become my focus and not socializing with humans! I will watch out for that. I'm hoping that the dog may help me meet people. There are dog parks near me and it would help me get out more. I've read that having a dog is just as good as a housemate health wise. My parents have already said they would doggie sit for me, they even offered without my asking when I told them I was going to try, so cool. Sorry your pet sitter didn't work out, coming home to my dog neglected and/or sick would be really upsetting.
