Fitting Tips
- Proper Fit: You should be able to fit 2 fingers between the harness and your dog's body
- Chest Strap: Should sit behind the front legs, not on the throat
- Neck Strap: Should not be tight enough to restrict breathing
- Movement: Your dog should be able to move freely without chafing
- Adjustment: Most harnesses have multiple adjustment points for a custom fit
- Growth: Puppies may need size adjustments as they grow
- Seasonal: Consider seasonal weight changes when fitting
How to Measure Your Dog
- Chest Girth: Measure around the widest part of the chest, behind the front legs
- Neck Girth: Measure around the base of the neck where the collar normally sits
- Back Length: Measure from the base of the neck to the base of the tail
- Weight: Use a pet scale or bathroom scale (weigh yourself, then weigh yourself holding your dog)
- Accuracy: Use a flexible measuring tape and measure snugly but not tightly
Important Notes:
- These are general size recommendations - individual dogs may vary
- Always check the specific manufacturer's sizing guide
- If your dog is between sizes, choose the larger size for comfort
- Consider your dog's body shape and proportions
- Test the fit before using for extended periods
- Monitor for signs of discomfort or chafing
- Consult a professional if you're unsure about sizing
