It really is in my opinion. I know I'd rather have my kids at someone's house receiving personal attention and not locked down surrounded by dogs that are also locked down. A lot less likely to have negative effects on their health such as Kennel Cough. Also not that it's necessarily good for the people providing the service, but usually prices are driven down by other people in your area so it's most likely going to also save you money.
Save on money, stress, and health benefits. Sounds like a good deal to me. Especially since first time users get to save $10 dollars off their first booking.
So if you are a provider Post your links below. Who better to watch a guest Mastiff than a Mastiff owner and lover. Or you can use my link I posted above and sign up to start making a little extra cash and provide some TlC to fur babies in need.
