Calming Collar for Large Dogs, Adjustable Pheromone Collar

A 70-pound dog shaking during a thunderstorm is a lot of worried dog to comfort. Many calming collars are sized for cats and toy breeds, leaving bigger dogs with a collar that barely reaches around their neck. This calming collar comes in a longer 65 cm length, as well as 56 cm and 38 cm options. It releases a blend of pheromones and plant essential oils for up to 30 days, and you can buy one to try it or stock up with a 2 or 3 pack.

Sized for Bigger Necks

The 65 cm (about 25.6 in) length gives large breeds enough collar to fit comfortably, with extra you can trim away. The 56 cm (about 22 in) option suits medium to large dogs, while the 38 cm (about 15 in) length covers small dogs and cats.

The blend is citronella-free and described by the maker as hypoallergenic and non-addictive. It's also waterproof, so it can stay on through swims, baths, and rainy walks.

Key Features

• Three lengths: 38, 56, or 65 cm to fit small, medium, and large dogs.
• Trim-to-fit: Adjust the length, then cut away the excess.
• Up to 30 days per collar: Replace every four weeks for steady release.
• Waterproof: No need to remove it for water or wet weather.
• Flexible pack sizes: Choose 1, 2, or 3 individually sealed collars.

Pick Your Pack

Not sure how your dog will respond? Start with a single collar and see how the first month goes. If it becomes part of your routine, a 2 or 3 pack keeps fresh collars sealed and ready for the next few months, or covers more than one pet in the house.

A Calmer Routine for Big Dogs

Large dogs feel stress from the same triggers as small ones: fireworks, thunder, car rides, vet visits, and long hours home alone. A calming collar works quietly in the background during all of it. Pair it with a secure, familiar resting spot, like a crate from our dog crates collection, to give your dog a place to settle.

Frequently Asked Questions

Will the 65 cm calming collar fit a large-breed dog?

It fits many large breeds. Measure your dog's neck and make sure the collar can wrap around with room for two fingers underneath. Very large or giant breeds may need a longer collar.

How quickly will I notice a difference in my dog?

It varies. Some dogs respond within days, while others take longer or show subtler changes. Wear time, surroundings, and the individual dog all play a part, so give it a few weeks.
