The Collar Sizing Mistake Most Dog Owners Make (And How to Fix It)

Why Proper Collar Fit Matters

A poorly fitted collar isn't just uncomfortable—it's a safety risk. Too loose, and your dog can slip out mid-adventure. Too tight, and you're restricting breathing and causing unnecessary stress. Yet most dog owners make the same critical mistakes when measuring and choosing a collar.

The Problem: Two Myths That Lead to Bad Fits

Myth #1: Collar Sizes Are Universal (S/M/L)

Most dog parents assume collar sizes work like clothing—small, medium, large. But here's the truth: every single company sizes differently, especially handmade small businesses like Wildside.

A "medium" from a big-box store might fit a 14–18" neck, while another brand's medium fits 12–16". There's no industry standard. That's why measuring your dog's actual neck circumference is the only reliable way to get the right fit.

Myth #2: Measuring Your Dog's Neck = Collar Size

Here's what 90% of dog owners get wrong: they measure their dog's neck, then order a collar in that exact size. But a collar isn't a necklace—it needs room to sit comfortably without choking or sliding off.

The result? Collars that are either dangerously loose or uncomfortably tight, leading to returns, frustration, and dogs that associate collar time with discomfort.

The Two-Finger Rule (The Right Way)

Professional trainers and veterinarians recommend the two-finger rule:

1. Measure your dog's neck at the widest point with a soft measuring tape
2. Add 2 inches to that measurement (or enough space to comfortably fit two fingers between the collar and neck)
3. Order the collar size that falls within that range

For example: if your dog's neck measures 14 inches, you'll want a collar that adjusts to approximately 16 inches when fastened.

Width Matters: Why 1.5" Collars Are a Game-Changer for Big Dogs

Most collars you'll find—whether at big-box stores or even small businesses—are 1 inch wide. It's the industry standard. But at Wildside, we also offer 1.5-inch wide collars for larger dogs, and once you try one, you'll never go back.

Why Wider Is Better for Big Dogs

A wider collar distributes pressure more evenly across your dog's neck. This is critical for larger breeds, because even a little bit of pulling on a thin collar can put dangerous pressure on the delicate trachea area and cause long-term damage.

The 1.5" width also:

• Shows off designs better on fluffy dogs (like Goldens) or dogs with longer necks
• Features stronger, more durable buckles built to handle the strength of big dogs
• Feels more comfortable for dogs that pull occasionally or wear their collar all day

If you have a dog over 50 lbs or a breed prone to pulling, the 1.5" width is worth every penny.

Quick Fit Check After You Buckle

Once the collar is on, do a quick safety check:

• Two-finger test: You should be able to slide two fingers comfortably between the collar and your dog's neck
• No slipping: The collar shouldn't slide over your dog's head when gently pulled
• No choking: Your dog should breathe, bark, and move freely without restriction
