DogiDuty app - DogiDuty offers an optional specially tailored approach to sending e-mail reports after each walk, or dog sitting session. However, I don't use this. I've found it good for keeping dog walking client/dog info in one place. Easy to contact owners if anything comes up. It could do with having a section for addresses and vets though. And a booked walks diary would be great. But still good for the basics.
