Collar is clean & in perfect condition. Only put on my pet a few times when trying on. It fits my 80lbs dog with a lot of wiggle room for larger breeds. Please do your own research on this product as it is very complex & requires a lot of time to set up & get your pet acclimated. Selling it because i have finally paid it off 😅 and still haven’t gotten around to using it/finishing the training portion of it so, posting here to see if it gets any attention. i have all parts and pieces including the box. Please ask any questions you have!
