The SpikeVest is similar to our original CoyoteVest but it uses Velcro instead of snap buckles. Just like the CoyoteVest the purpose of the SpikeVest is to help slow down or prevent a surprise attack and give you enough time to react before serious injury occurs.

Naturally the SpikeVest includes a full set of removable chrome spikes*. The spikes are made from very hard plastic and they're not dangerous to handle, but with enough pressure they're sharp enough to hurt. The spikes provide an important line of defense but Velcro makes them easy to remove whenever you want. (If you want black chrome spikes instead of the standard silver chrome spikes just let us know in your order notes.)

The SpikeVest is entirely constructed with a super tough puncture resistant Cordura® fabric that can resist sharp canine teeth and features a large collar to protect the back of the neck. It wraps around your dog easily and stays snug and secure with two wide Velcro belts. There's a D-ring for connecting your leash and reflective features that make your dog more visible at night. It's water repellent and there are no metal parts that can rust. It's hand-washable with a mild detergent. 

Please be aware that even though the Velcro works well it could be less secure than snap buckles if not used properly.

If you're concerned with wild predators our CoyoteWhiskers and HawkShield accessories are highly recommended for the SpikeVest.

Choosing a Size

Choosing the correct size vest is easy -- the most important thing is the length of your dog's back. The collar and the waist are very adjustable but if you order a vest that is longer or shorter than the length of your dogs back it will not fit properly and you will need to exchange it. If your purchasing as a gift we do offer gift cards that can help keep your secret. 

All you have to do is measure the length of the back from the base of the neck to the start of the tail -- make sure the dog is standing up and not sitting.


  • If your dog's back length is between 8 inches and 9.75 inches, the recommended SpikeVest size would be a X-Small.
  • If your dog's back length is 15+ inches, the recommended SpikeVest size would be a medium.
  • The large vest is for large dogs. If your dog's back is 20+" or more you can use the large vest. The large dog usually weighs over 32+ lbs to 65 lbs.
