Who knew a dog bowl could be so aesthetically pleasing?! The stand keeps it at just the right height, and my dog seems to enjoy mealtime even more now! ❤️

What Pet Parents Are Saying About KOSTON
The perfect dog harness for large breeds. Our Sharpei has a wide chest and most harnesses don't fit him. Except for this dog harness from KOSTON!
