fouFIT - Cooling Collars

This collar features a convenient Velcro closure for easy application. Its innovative gel slowly evaporates once activated, providing up to 2 days of refreshing coolness. Designed to replicate the natural cooling process of sweating in dogs without sweat glands.   When submerged in water, the cooling collar activates its special polymer beads. As the water evaporates, it pulls heat away from your dog, providing them with a cooling effect. Since dogs do not have sweat glands, the collar replicates the natural process of cooling through evaporation. The collar stays cool for up to 48 hours and is secured with Velcro. Material: Cotton, polymer beads. Sizing (Neck Circumference):  Measure your dog's neck with a tape measure.  Small: 10" (25.5cm) - 12" (30.5cm) Medium: 12" (30.5cm) - 15" (38cm) Large: 15" (38cm) - 18" (45.5cm) Product Dimensions: Small: 14" x 2.5" Medium: 17" x 3" Large: 20.5" x 3.25"
