How to Measure Your Dog
Follow these simple steps for accurate measurements
Chest Measurement
Measure around the widest part of the chest, just behind the front legs. This is the most important measurement for harness sizing.
Neck Measurement
Measure around the base of the neck where a collar naturally sits. Use this measurement for secondary confirmation of size.
Weight Confirmation
Use your dog's weight as a secondary check alongside the chest measurement for the most accurate sizing results.

Frequently Asked Questions
Get quick answers to the most common harness sizing questions
For active dogs, running, and hiking, always choose a harness. Harnesses distribute pressure across the chest instead of the throat, preventing breathing issues and providing better control. Collars are fine for well-trained dogs on casual walks.
Front-clip attachments help reduce pulling by redirecting your dog toward you when they pull forward. Back-clip attachments are better for trained dogs and running activities. Many premium harnesses offer both options.
Quality harnesses typically last 2-3 years with regular use. Replace your harness when you notice fraying, damaged hardware, or if your dog's size changes significantly. Check hardware monthly for signs of wear.
Replace when you see:
- Frayed webbing or fabric
- Bent or damaged buckles
- Worn or sharp D-rings
- Stretched elastic components
- Padding deterioration
It's best to remove harnesses when not needed to allow skin to breathe and prevent chafing. If you need all-day wear, choose ultra-comfortable options with breathable materials and padding.
For escape artists, consider harnesses with additional belly straps or full-body coverage. Ensure proper fit (1-2 fingers under straps) and consider sizing down if your dog is between sizes.
Escape-proof strategies:
- Proper chest measurement is crucial
- Consider a 5-point harness design
- Check fit after every adventure
- Size down if between sizes
- Look for anti-slip features
