The Houndd Co. House Collar is designed with comfort and practicality in mind. Lightweight and adjustable, it’s perfect for everyday wear, ensuring your dog always has your contact details on them. Simply slide the knots to adjust the fit, making it suitable for a wide range of breeds. Sizes for Every Dog (and You!): XS: 12–23 cm (4.7–9.1 inches) (best for italian greyhounds, miniature breeds) S: 17–36 cm (6.7–14.2 inches) (best for whippets, maltese, small breeds) M/L: 20–44 cm (7.8–17.3 inches) (best for greyhounds) XL: 38–72 cm (15–28.4 inches) (best for large breeds) Want the matching bracelet too?Just choose “Bracelet (sold separately)” from the size options and add it to your cart separately. The bracelet and collar are sold individually. Safe Design: The collar only tightens if both ends are pulled at the same time, reducing the chance of accidental tightening. The two knots are not fixed, meaning if the collar gets caught on something, it will loosen allowing your dog to slip out safely. You can see how this works in the video included in the product photos. 📌 Please note: This collar is not designed for walking. We don’t recommend leash attachment.
