I also have that we are a pet friendly home ( we have a 95lbs dog and bird) and I don't have it in my contract either. Like Crayola kiddies, our dog is part of the interview as she have to see him and how he interacts with my kids and their's.
I also have quite a few pics of him on our website too. He's our mascott!!

Some have told me not to put that we have pets as it deters people from contacting us but I had an interview once where I didn't tell them that I had our dog and the father had a bad experience with dogs and even if he got to know our dog, it wouldn't have worked for them as his experience has carried with him and he is extra cautious with his little one. I feel honesty and upfront is the way to go- I don't say 95lbs Golden retriever but it's mentioned before interview so I don't suprise them.
