Size & Fit Guide
Fit & Measure Guide
A better fit starts with a simple measurement.
Use this guide to find the right size for your dog’s collar or harness before you head out together.
How to Measure
Measure while your dog is standing naturally.
Use a soft measuring tape and keep it close to your dog’s body without pulling tight. Your dog should be standing in a relaxed position so the measurement reflects how the gear will fit during normal movement.
Neck Girth
Measure around the lower part of your dog’s neck, where a collar naturally sits. The tape should rest close to the coat without pressing into the skin.
For collars, leave enough room to fit two fingers comfortably between the collar and your dog’s neck. For harnesses, use the neck girth together with the chest girth to choose the best size.
Chest Girth
Measure around the widest part of your dog’s chest, just behind the front legs. Keep the tape level around the body and avoid measuring too close to the armpit.
Chest girth is usually the most important measurement when choosing a harness. If your dog is between harness sizes, start by matching the chest girth first, then adjust the neck and body straps for a secure, comfortable fit.
Collar Size Chart
Choose by neck girth first.
Use your dog’s neck girth to find the right collar size. The fit should feel secure around the lower neck without pressing into the skin or slipping over the head.

Fit Check
After fastening the collar, you should be able to fit two fingers comfortably between the collar and your dog’s neck. The collar should feel secure, but never tight.
Breed examples are only a reference. Dogs of the same breed can vary by age, coat thickness, body shape, and weight, so measuring your dog is always the best way to choose.

Fit Check
A well-fitted harness should sit flat against your dog’s body without rubbing behind the front legs. It should feel secure once adjusted, while still allowing your dog to walk, sit, and turn naturally.
If your dog is between sizes, prioritize the chest girth first, then adjust the neck and body straps for balance. Breed examples are only a reference, so measuring your dog is always the best way to choose.
Leash Comparison
Choose the leash that fits your pace.
Daily Step Leash is built for simple everyday movement, while Trail Dash Leash adds more length, stretch, and outdoor-ready control for active days outside.
Leash Use Guide
Four ways to move through the day.
Our adjustable leash design lets you switch between everyday hand-held control, crossbody walks, waist-worn movement, and short tie-out moments when used with care.
01 / Hand-Held
For daily walks and close control.
Use the leash in hand-held mode when you want simple, direct control on sidewalks, in busy areas, or during quick outings. This is the easiest setup for everyday walks when your dog needs to stay close.
02 / Crossbody
For hands-free walking.
Wear the leash across your body when you want more freedom for your hands while keeping your dog connected. This mode works well for relaxed walks, light errands, or moving through your routine with less fuss.
03 / Waist-Worn
For steady movement together.
Secure the leash around your waist for jogging, light hiking, or longer walks where you want your arms free. Keep your dog at a manageable distance and use this mode only when the environment allows safe movement.
04 / Tie-Out
For short, supervised pauses.
Use tie-out mode only with a fixed or weight-bearing object, and always under supervision. This setup is intended for brief moments when you need both hands free, not for leaving your dog unattended.
