I like how easy it was to set up my account for dogs in other states! There are so many different features available which makes this software very useful when working at multiple locations simultaneously (i.e., more than one person can access your data). The interface could be easier overall but there have been some improvements made since we started using them over 5 years ago now as well. A couple of minor things here & there - no big deal though just something small they've fixed or added recently :) Great all around solution if looking into any type of dog tracking/management program. We use their service primarily because our previous vendor would not provide us full visibility across state lines nor did they offer a mobile app option either.
