Everything came as expected, beautifully crafted! Fits my Maggie girl perfectly, and the colors are great. Between ordering & shipping it didn’t take long to receive my collars. Very happy and plan to purchase from here again.

Biothane Leash Wrap Alternative, Custom Text, Optional: Twist Lock Carabiner

I needed something that would stand out against his leash while also being easy to clean for my service prospect and I had been eyeing this shop for a while. My bonus check came around and I immediately ordered. I will definitely be ordering more from them in the future and also may get a message tab for my reactive rescue!

This was a gift for another service dog team! They said it was the most comfortable strap they have had and works great! They use it for forward momentum and grounding!

Collar Me Impressed! Just got a personalized collar for my dog and it's awesome! 🐶 It’s super sturdy and well-made. The colors are exactly like the photos – vibrant and spot-on. I was excited and impatient and had questions about timing, but the seller was super kind and responsive and shipping was just as indicated.  Gromit and I couldn't be happier with this purchase! Highly recommended!
