Column type
The right collar for your dog will depend on your dog’s coat type, breed, training, and the basic case you are using. A few main types of collars are flat collars, martingale collars, head collars/head halters, and rolled collars. There are also GPS collars and lighted collars that add additional features.
Flat collars are generally the best option for most dogs, especially if they are leash trained and/or leash trained. Martingale and slip collars are options for flight-prone dogs, while head collars / head halters are good options for dogs that pull or are still working on leash training. Rolled collars are ideal for dogs that have been leashed for long periods of time and their coats may be damaged from tight flat collars.
Slip collars and halters/head collars should be used under the supervision of a professional dog trainer. These types of equipment can be dangerous if not installed and conditioned properly, so ask your dog trainer if you would like to use one of these options.
Note that this section does not include prong collars or e-collars, which Treeline does not recommend.
Material and durability
Nylon, polyester webbing, coated webbing (biothane), and leather are all material choices for dog collars. Nylon and polyester webbing are the most commonly used materials and are budget friendly, often durable, and flexible. The main disadvantage is that they are not waterproof all the time.
Biothane or coated webbing is waterproof, but generally stronger than other options. It’s a plastic-y material that can easily be wiped off and doesn’t repair well. Biothane is the best option for dogs that swim a lot or walk where they can get dirty or muddy.
Leather dog collars are also available, but there is much variation in the quality of leather options. They can last remarkably long and soften with use, or they can be brittle and of poor quality. We’ve avoided leather options for this guide, as it’s hard to find well-made and affordable options (both in terms of price and seller).
For environmentally conscious dog owners, there are also dog collars made from partially recycled materials, such as Ruffwear Web Reaction Reflective Dog Collar.
Hardware quality
Hardware is the most common point of failure in budget collars, especially buckets and D-rings. Buying a collar with sturdy hardware (preferably strength tested) is the first way to keep your dog safe while out and about. A ring that bends under the pressure of the leash or rotates under the collar is a safety and usability issue.
The main types of collar straps include the plastic side release, the metal side release, and the regular hole metal strap.
Fit and size
To measure the dog’s neck for the collar, use a flexible measuring tape (or a piece of string or a rope dog), and wrap it around your dog’s neck. You should be able to slide two fingers under the measuring tape to get a collar that fits properly and isn’t too tight.
Note that sizing varies widely across brands and neck circumference measurements are often more reliable than brand or weight recommendations.
Safety considerations
The main safety considerations for dog collars are the reliability of the hardware and the stiffness/pressure on your dog’s neck.
Always find a dog collar that is right for your dog’s weight and size. A large, sturdy breed such as an Alaskan Malamute or Samoyed should not be walked with a small strap collar designed for small dogs, even if it fits their neck well. Thicker collars with thicker straps are generally stronger and more durable than thinner options, so they’re better for larger, stronger dogs.
On the other hand, a collar that is too big or too heavy for a small breed dog may be uncomfortable for him and may irritate him during walks or training.
You should also choose a collar that is not too tight around your dog’s neck. You should be able to slip two fingers under your dog’s collar and wiggle it. Anything too tight can affect how well they can breathe.
Tightness/pressure on your dog’s neck is another great safety measure. Collars combined with a pulling dog can cause pressure sores, coat damage, and in extreme cases, tracheal damage.
Any pulling dog should not be walked on a collar alone. A head halter or dog harness designed to pull is generally a safe option that will not cause damage to your dog’s body, but should be used and introduced under the supervision of a professional dog trainer.
Visibility can also be a safety consideration—more on that below.
Appearance and appearance
Keeping your dog safe seems to keep him safe. If other dogs, hikers, walkers, joggers, bicyclists, vehicles, and wildlife can see your dog, you are less likely to have a negative incident. Choosing a bright collar or a lighting collar it will keep your puppy visible in low light conditions.
