It's OK! Catching the flag is part of the fun for your pup! The kit ships with a roll of flags, so you'll be all set in case you need to tie a new one back on - if your pup tears it up!
If you are concerned that they might eat the flag see: What if my dog eats the flag?
And SwiftPaws Home has a built-in stall feature which will stall and stop the motor if your dog steps on the line or grabs the flag. This is one of a few safety features that differentiate our home from our professional equipment.
For the full list of the SwiftPaws Home safety features, you can download the latest version of the Welcome Manual by going to www.swiftpaws.com/getstarted under the "Click for Downloads" & clicking on the Welcome Manual link
