SpikeVest helps protect your beloved dogs and puppies from being attacked, keeping your furry babies safe

The SpikeVest: Maximum Protection with Velcro Convenience The SpikeVest is designed to slow down or prevent surprise attacks, giving you the critical time needed to react before serious injury occurs. Similar to our original CoyoteVest, the SpikeVest swaps snap buckles for high-strength Velcro for a faster, adjustable fit. Key Features & Defense Puncture-Resistant Fabric: Constructed with super-tough ballistic material to resist sharp canine teeth. Kevlar® Reinforcement: A large collar reinforced with genuine DuPont™ Kevlar® protects the vulnerable throat area. Full Spike Set Included: Comes with removable chrome spikes for the neck and two spike strips for the back. These hard plastic spikes are safe to handle but sharp enough to deter a predator. High Visibility: Built-in reflective features ensure your dog is seen at night. All-Weather Durability: Water-repellent fabric with zero metal parts—nothing to rust! Fit & Care Secure Attachment: Two wide Velcro belts keep the vest snug and secure. Leash Ready: Includes a sturdy D-ring for easy leash connection. Easy Cleaning: Hand-wash with mild detergent and air dry in the shade. (Do not use a dryer). Note on Velcro: To ensure maximum security, keep Velcro clean of hair and dirt. While highly effective, Velcro can wear over time and may be less secure than snap buckles if not properly maintained. Choosing the Right Size The back length is your most important measurement. Measure: From the front shoulder to the start of the tail. Stand Straight: Ensure your dog is standing (not sitting). Measure Straight: Hold the ruler/tape in a straight line; do not follow the curve of the dog’s back.

And if you're still not sure we can help. Just email us your measurements and a good side-view picture of your dog and we can give our best suggestion. If your dogs waist or neck is larger than the ranges shown we recommend ordering an Extender for the waist and/or the neck. If your dogs waist is at the lower end or less than the given range we recommend ordering a Stay Strap to prevent the flap from dangling.
