The adjustable length of 25.6 inches allows it to fit a variety of breeds, and the stylish color options add a fashionable touch.

However, some potential drawbacks include the need for careful adjustment to ensure a snug fit, as a loose collar may not provide optimal protection. Additionally, while the collar is generally safe, it's important for pet owners to monitor their dogs for any signs of irritation or allergic reactions, especially in puppies and senior dogs.

However, it's important to note that the collar is only suitable for dogs and puppies aged 12 weeks and older. While it can be worn with your dog's regular collar, some users might find the fit slightly bulky or uncomfortable for very small dogs.
