These padded elbow sleeves are absolutely the very best quality. We use two layers of plush fleece which makes up the padded sleeve, they are double thickness and extra long lasting. Great care has been taken with this design, upholstery grade foam (1.25cm in thickness) has been sewn inside between the two layers of fabric which cushions and comforts your dog's elbows. This design ensures the edges of the pads don't rub up uncomfortably on your dog's skin and also keeps the pads fixed perfectly in place. We also don't use thick buckles to adjust the strap over your dog's back, which over time would cause stress. These sleeves are the ultimate solution to help ensure your dog leads their fullest and happiest life, especially in their older years. This product particularly helps relieve discomfort caused by hygroma, calluses, or just aging in general. ADJUSTABLE Dog Elbow Protection which you will not find elsewhere! Quality DURAFOAM padding (upholstery grade 1.25cm) has been encased and sewn between the two layers, making sure there is no rubbing or uncomfortable edges that can dig into your dog's skin. Please let me know if you need help and sizing advice. IMPORTANT SIZING INFORMATION. Measure you dog's front leg from elbow down to paw. The correct size to order would be an actual sleeve length (see actual sleeve lengths below) which is a few centimeters less than the measurement you have taken. This allows the cuffs to rest a distance above your dog's paws. These sleeves are MACHINE WASHABLE and ROBUST, they will last for many years.
