One Vest, Four Functions — Swim, Cool, Warm & Rehabilitate Your Dog Year-Round
The JK9® Multivest is Julius-K9®'s most versatile product — a 4-in-1 dog vest that adapts to every season and situation. Whether your dog is hitting the water, recovering from surgery, or staying cool on a summer hike, this single vest does it all.
- ✅ Swim vest — floating foam pads keep your dog buoyant and safe in the water
- ✅ Cooling vest — dip in water and the 3D mesh fabric actively cools your dog (remove foam pads)
- ✅ Dog coat — insulating layer to keep your dog warm in colder months
- ✅ Rehabilitation harness — reinforced back handle and rear strap for ergonomic, spine-aligned lifting
- ✅ Lightweight & quick-drying — 3D mesh dries fast and stays comfortable all day
- ✅ Improved buckle placement — easier to put on at neck and abdomen, secure fit every time
- ✅ Optimized lifting point — better weight distribution for safer lifts for dogs with limited mobility
