Thank you for this outstanding product! Our little terrier inhaled a stray foxtail spikelet on an otherwise pristine sidewalk, requiring expensive surgical removal. With foxtails springing up in yards, fields, even sidewalk cracks, our walks had become tense and frustrating – we had to be hyper vigilant and tug our dog away from any possible hiding place for those nasty spikelets. The OutFox Field Guard brought fun and relaxation back to our walks! Our dog adjusted to the Field Guard within minutes and now happily bounces down the sidewalk and trails, sniffing and exploring with ease and safety.
