It's OK! Catching the flag is part of the fun for your pup! Your kit shipped with a roll of flags, so you might have to tie a new one back on!
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 home and 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
