Ash loves his new collar! He hates wearing collars and finding a Fi compatible collar that wasn’t 1 inch thick in his size was a challenge. This collar works perfectly and I love how complimentary the colors are. Thank you!
Ash looks very handsome in his new collar! Thank you Ricki, glad we were able to help you both!
I needed something well made and this collar is definitely it! My husky Bruno can be a handful and his collar not only fits him perfectly but also is as strong as he is in times Bruno sees a bunny on a walk and gets crazy.
It's wonderful to hear that Bruno is loving his new collar! Thank you Gia for your awesome review helping Bruno find the perfect HTH gear!
