12" Monster Bully Sticks

Pet O’ Clock 12” Monster Bully Sticks – The Ultimate Power Chew for Large Dogs

A big dog needs a big chew, and our 12” Monster Bully Stick is built to handle the mightiest of chewers. Designed specifically for giant breeds like Great Danes, Mastiffs, and St. Bernards, this extra-thick, long-lasting chew is perfect for powerhouse chewers that demolish regular treats in minutes.

If your dog makes quick work of standard Bully Sticks, it’s time to level up. These protein-packed chews provide hours of entertainment while delivering essential amino acids to support strong muscles, a healthy coat, and overall well-being. Not only are they delicious and satisfying, but they also help combat boredom, anxiety, and teething discomfort—all while keeping your dog’s teeth clean.

Safety First!

Always supervise your dog while giving any chew or treat, and ensure they have fresh water available. Remove small or broken pieces to prevent choking hazards. Consider your dog’s size, chewing habits, and dietary needs before selecting treats. If this is a new treat for your pup, introduce gradually to avoid stomach upset.

Always supervise your dog when offering any PetO’Clock chew, and keep fresh water on hand throughout chewing.

For puppies or dogs new to our protein-rich treats, introduce them gradually: limit to one stick per day for the first 3–5 chews to help prevent stomach upset. Once your pet’s digestive system has adjusted, you can feed at your discretion.
