How to Adjust your Dogs Collar: A Step-by-Step Guide
How to Measure Your Dog’s Neck
Measure your dog’s neck so that you can choose the right size collar. To do this, you’ll need a cloth measuring tape.
- Place the measuring tape around your dog’s neck just behind the ears.
- Make sure the tape is snug, but not too tight.
- Read the measurement on the tape.
Understanding Your Dog Collar
Dog collars come in a variety of styles, but most share some common features that affect adjustability. Here’s a quick rundown:
- Buckle: This is the clasp that secures the collar around your dog’s neck.
- D-ring: This metal ring is where you attach the leash.
- Strap: This adjustable part of the collar determines the fit.
- Tri-glide (or slider): This small piece of plastic slides up and down the strap, allowing you to adjust the size.
Types of Dog Collars
Flat collars
These are the most basic and common type of dog collar. They are typically made of nylon, leather, or cotton and have a D-ring for attaching a leash and ID tags. Flat collars are a good choice for well-trained dogs who don’t pull on the leash.
Buckle collars
Buckle collars are similar to flat collars, but they have a buckle closure that makes them easier to put on and take off. Buckle collars are a good choice for most dogs.
Martingale collars
Martingale collars are designed for dogs who can easily slip out of a traditional collar. They have a loop that tightens gently when the leash is pulled, but it loosens up when the pressure is released. Martingale collars are a good choice for sighthounds, such as Greyhounds and Whippets, as well as other breeds with narrow heads.
Head collars
Head collars, also known as halters, fit over a dog’s snout and behind their head. They can be very effective in helping to control dogs who pull on the leash. However, head collars are not appropriate for all dogs, and some dogs may find them uncomfortable.
Smart collars
Smart collars are a relatively new type of dog collar that incorporates technology such as GPS tracking, activity monitoring, and even health monitoring. Smart collars can be a great way to keep track of your dog and learn more about their activity levels and health.
Dog Collar Size Chart (By Neck Measurement)
This chart is a starting point, and breed variations can occur. If your dog falls between sizes, it’s usually better to choose the slightly larger size for adjustability.
| Neck Measurement (in inches) | Collar Size (in inches) |
| Up to 8″ | Extra Small (XS) |
| 8″ – 12″ | Small (S) |
| 12″ – 16″ | Medium (M) |
| 16″ – 20″ | Large (L) |
| 20″ – 24″ | Extra Large (XL) |
| Over 24″ | Giant (G) |
Signs of a Poorly Fitting Collar
Even with careful measuring and adjustments, issues can arise. Here’s how to identify a collar that’s not quite right:
Too Loose
- You can easily slip three or more fingers under the collar.
- The collar slides around easily on your dog’s neck.
- Your dog manages to slip out of the collar during walks.
Too Tight
- You can barely fit one finger under the collar.
- The collar leaves red marks or irritation on your dog’s neck.
- Your dog coughs or gags when the leash is pulled.
- Your dog constantly scratches at their neck.
Two Finger Rule
- For small breeds, you should be able to slip one finger between the collar and the neck.
- For medium-sized breeds, use two fingers.
- For larger breeds, aim for three fingers.
- Slide two fingers comfortably between your dog’s neck and the collar.
- The collar should feel snug but not tight. You should be able to move your fingers around a bit.
- If you can fit three or more fingers, the collar is too loose.
- If you can only fit one finger with difficulty, the collar is too tight.
This rule ensures your dog has enough breathing space and movement while keeping the collar secure.
Pro Tip: After adjusting, always double-check by gently pulling on the collar. It should feel secure but not restrict movement.
1. How often should I adjust my dog’s collar?
You should check the fit of your dog’s collar regularly, especially when they are growing or if they gain or lose weight. Puppies, in particular, need frequent checks as their necks grow quickly.
2. My dog hates wearing a collar. What can I do?
Some puppies may need time to adjust to wearing a collar. Introduce the collar gradually, letting them wear it for short periods at first and offering praise and treats for positive reinforcement.
3. Is a harness a better option than a collar?
Harnesses can be a good alternative for some dogs, especially those prone to tracheal issues or neck injuries. However, collars are still essential for identification tags and leash attachment.
4. How to Adjust a Dog Collar Properly
Use a flexible tape measure or a piece of string.
Place it around your dog’s neck where the collar would sit.
Make sure it’s not too loose or too tight.
Note the measurement in inches or centimeters.
