It was very thick. I wouldn't recommend it for a dog under 25 lbs. Also, it wasn't the best quality. My dog itched his head and there was already a pull on the ribbon side of the collar. I doubt it will last very long. Spoiled Sweet response :: Thank you for your feedback. Our apologies that you did not take notice to the item description that explains this collar is a ribbon sewn onto nylon and that it is 1 inch wide. While there is no minimum weight requirement, if you prefer a lighter, thinner collar we do have many other options available. You'll find the sizing (width) and details right in the item description. Unfortunately, a ribbon collar might not be the best choice for pups with long or sharp nails, as it is a ribbon and ribbons can be snagged. Based on your feedback, we'd point you towards the Yellow Dog Design line of nylon collars or leather.
