A properly fitted collar should let you slide two fingers flat between the collar and your dog's neck — snug enough that it won't slip over the ears, but loose enough not to restrict breathing or rub the skin raw. Both a too-loose and a too-tight collar create real risks, not just discomfort.
The two-finger rule
With the collar fastened, slide two fingers underneath it, side by side. If they fit snugly with light resistance, the fit is right. If you can fit more than two fingers, or the collar spins loosely around the neck, it's too big.
Signs the fit is wrong
- Too tight: Fur wearing away, red or irritated skin under the collar, or coughing when on leash.
- Too loose: Collar rotates freely around the neck, or slips over the head during walks or play.
Measuring before you buy
Wrap a soft measuring tape around the base of your dog's neck, where the collar naturally sits, then add about 2 inches for the two-finger gap. Compare that number to the actual size range on each Ziva Paws collar listing rather than guessing by breed or weight alone.
Quick recap
Use the two-finger rule, watch for signs of rubbing or slipping, and measure your dog's neck directly before choosing a size. Orders over $75 ship free, code ZIVA10 takes 10% off, and orders over $120 automatically save 15%.
