Why Dog Collars Must Match Breed and Size
Here’s the thing—no two dogs are alike. A collar that works perfectly for a Pomeranian might be a complete disaster for a Rottweiler.
Here’s why breed and size matter:
- Different neck sizes mean different fit requirements.
- Strength and activity level demand different materials.
- Fur density impacts comfort and breathability.
- Behavioral traits (like pulling or escaping) affect the collar type you need.
Choosing a collar based on your dog’s specific needs reduces the risk of injury, helps with better control, and makes your pup’s walks way more enjoyable.

How to Measure Your Dog’s Neck (The Right Way)
- Use a soft measuring tape (or string and ruler).
- Measure at the base of the neck, where the collar will sit.
- Add extra length based on breed size:
- Small dogs: add 1 inch
- Medium–Large dogs: add 2 inches
- Small dogs: add 1 inch
- Use the two-finger rule: You should be able to slide two fingers comfortably between collar and neck.
Quick Tip:
Try on the collar and monitor your dog for the first few hours. If they scratch, shake, or tug excessively, it might be too tight—or too loose.
