I use Rover pretty often for medium-term dog care for trips and such. It usually costs me $400-$1000 for a week or two so it definitely provides a valuable service and good revenue.

Jeez I can take my two dogs to a full on dog ranch for a week for less than that. They get to play all day with dogs and run around on an old farm... dog ranch = dog kennel

Options in major cities are much more limiting. The nice places like that are absurdly expensive. Rover helps make it more affordable to board your pup for longer trips.

My building in Miami has a 24 hour dog walker that you can call or text, and if you've got an apple device, you can even facetime with your dog, and it's part of my Condo Fees. Because of that, I really have no need for Wag or Rover.
