Large & XL Dog Collars

Strength where it counts, comfort everywhere else. On a large dog the hardware takes real force — every lunge at a squirrel loads the D-ring and buckle — so ours are welded stainless steel and a heavy-duty side-release that won't pop under pressure. The soft webbing spreads that force comfortably across a big neck, and the adjustment range keeps the fit right as seasonal coats come and go.

Sizing matters more, not less, at this end of the chart: measure the base of the neck to the skin and add two fingers. Our dog collar size chart has the walkthrough, and the sizing calculator does the math. For the very biggest necks, see our Great Dane fit guide.

A wider neck gives a pattern room to read from across the park, so this is where bold prints shine. Midnight Sky is the timeless cool pick, Breezey Blue suits the sporty lake-and-trail crowd, and Matcha Gingham is quiet class on a rich coat. For the full styling tour, our cool collars for big dogs roundup rates eight looks by coat color.
