Great Product

I am very pleased with this product. My dog is a 15lb Havanese and the small fits him perfectly. It's like he is wearing a bracelet. It doesn't seem to bother him at all. Set up with the QR code was quick and easy. I've been telling everyone about this great product. Thank you

Love these collars

My husband and I are so glad we found undercollars. Our dogs don't wear collars but they wear these day and night. I like that the collars are elastic and loose fitting-- the dogs don't mind them. I did have to create a new paper "tag" to replace the ones that come with the collars. I find that using thicker paper keeps the tag from sliding out and I put tape over it so the plastic covering is taped to the tag. My favorite part about these undercollars is the QR code and the websites for my dogs. I put ALL their info in so anyone who scans the QR code or goes to the individual website has everything needed to get ahold of my husband and I, my parents, or our vet, and has all informationregarding each dog at their fingertips. I feel 100% more at peace knowing my dogs wear undercollars. I find it a fantastic little investment and truly believe all pets that can, should wear an undercollar. You never know when it might just be the singular factor that brings your dog home to you!

Thank you for your kind review, we are happy when you are happy!

10/10 recommend

I love these collars and my dogs do too! They are comfortable! No more laying on metal or plastic buckles with a regular collar. Your dog is always safe with the undercollar on and 2 forms of id. I travel the country with my dogs and won’t go without our under collars!

Sizing off

I initially ordered a L then read the sizing chart and changed my order to XL based off the chart. I received eves the 2 XL collars. D tge yerre way too big I should have not bothered with the chart.

We gladly take exchanges for a different size in unused condition. We emailed you and asked what size is your pets neck. Please contact us. Thank you for your review.

These collars are a MUST!

My dogs are not allowed to wear collars when at home, after a near-death experience 7 years ago, in which one of my dogs got her tags stuck in some fencing in our yard. She had twisted around several times in an attempt to free herself and was choking, when thankfully my mom had gone outside and found the dog before she died! I have never been comfortable with my dogs not having identification on them, even when at home and even though they are both microchipped, since a collar or tags is the best way to get notified quickly if they were ever lost. I really love these Undercollars because they are comfortable for the dog, attractive and if they did ever get stuck on something (but this is highly unlikely due to the great design), the dog could free itself quickly. My dogs have 2 in several colors. I like one for daily wear, for going to the beach etc, and one I keep in like-new condition, for when we go out to a dog friendly restaurant, friend's house, etc. Also the QR scan code on these collars is an awesome feature! I previously had QR code tags on my dog's collars. These Undercollars do it all and SAFELY. I am a dogsitter and I recommend the Undercollars to all my dog parents!

WOW, thank you so much for that wonderful and thoughtful review! This is why we work harder and harder every day to keep our pets safer. It's customers like you that make every moment worth it!
