BARKLESS Basket Dog Muzzle, Size 5 for Large Dogs, Open Design for Training

The BARKLESS size 5 basket dog muzzle is designed to help manage nipping and scavenging during training, while its open basket allows dogs to breathe, drink, and take treats.

• Size 5 fits a snout circumference of 11¾–12½ in (29.8–31.8 cm) and a snout length of 4 in (10.2 cm) — compare both measurements before choosing.
• Open basket construction — lets your dog breathe, drink, and accept treats while wearing the muzzle.
• Removable collar loop — links the muzzle to a collar for added stability and helps reduce slipping.
• Quick-release neck strap and sliding adjuster — make it easier to put on and adjust the fit.
• TPE silicone construction — gives the muzzle a lightweight, flexible feel and a form-resistant basket for medium and large dogs.

This muzzle is made for situations where a dog needs help managing mild unwanted behaviors, such as nipping or picking up wildlife, rocks, and other items while out walking. It can also be used for vet visits and grooming. A muzzle is a training tool, so gradual introduction and active supervision are important parts of use.

How do I choose the right fit for this BARKLESS muzzle?

Choose this size 5 only if your dog’s snout measures within both listed ranges: 11¾–12½ in (29.8–31.8 cm) around and 4 in (10.2 cm) long. Measure your dog rather than relying on a previous muzzle size; breed examples are only a guide. Golden Retrievers and Labradors are examples of dogs that may fit, but individual measurements matter.

• This size is intended for large dogs.
• It is not designed for short-snout dogs, including French Bulldogs and Shih Tzus.
• Use the sliding buckle to adjust the strap snugly around your dog’s head.

What can my dog do while wearing the basket?

The open basket design allows breathing, drinking, and treat-taking. Its W-shaped construction keeps the cage opening away from the eyes, while the open structure supports airflow. Twisted sections on both sides of the strap help the muzzle fit different head shapes.

• The removable collar loop adds a connection point to help stabilize the muzzle.
• The quick-release buckle makes putting the muzzle on and taking it off easier.
• For a secure fit, adjust the strap; poor fit or adjustment can let a dog remove the muzzle.

How should I introduce and supervise the BARKLESS muzzle?

Introduce it with treats and short sessions so your dog can build a positive association with wearing it. The included guide covers sizing, use, and care. Keep your dog supervised whenever the muzzle is on; never leave a muzzled dog unattended, since stress or anxiety can create risks.

• Use it to help manage mild behaviors such as nipping and scavenging, not aggressive biting.
• Keep children at a safe distance and monitor interactions with other dogs.
• The muzzle is a training tool, not a toy.

This BARKLESS size 5 muzzle suits owners of medium or large dogs who need a basket-style training aid for walks, grooming, or vet visits and can measure their dog for fit. Its adjustable strap, collar loop, and open basket support supervised use while allowing everyday functions such as drinking and taking treats.
