Do you take back up contact info?

Yes. Remember you work for yourself, not Rover. You can ask for whatever you want.

I have all owners to fill out a Dog Info sheet that I've created, which asks for their phone number, address, vet info, vaccination info, emergency contact, as well as behavioral info. However, when it comes to emergency contact info, most of my customers put down their spouse/partner and usually they are traveling with that person. Rather worthless IMO. One person gave me her mother's phone number and the mother lives in another state. But I think that's going to be typical of people in my area, i.e., they are usually not from here. I feel I need to be more specific on my form that an emergency contact must be here. Oh well...
