Lots of people travel with pets. You could add pet friendly stops with access to veterinary care and possibly pet supplies or services.
Travel with Pets
Yes pleasssssse. Places for doggie breaks are needed when traveling
I saw Petco and Petsmart listed under "browse by category", and then "other"
I would gladly pay for an app that had parks and dog parks within 5 miles of an interstate exit. A pet friendly road warrior app would have a big audience!
