Train your pup like a pro 🐶 So we got a thicker and stronger collar that will be able to grow with Bing(our dog). We also got the hypoallergenic prongs. The original prongs that come with the educator(E-collar) can cause unwanted skin irritation/injury for dogs with sensitive skin. So these hypoallergenic prongs are a great investment so you don’t have to worry. LTKHome LTKdayinmylife LTKmomlife
