Coastal Pet Adjustable Puppy Collar — Breakaway Safety — for Large Breed Dogs — Great Dane, Mastiff, Rottweiler

Coastal Pet's breakaway puppy collar is engineered for the explosive growth rate of large breed puppies — German Shepherds, Labrador Retrievers, and Golden Retrievers can gain 10 lbs per week in the 8–16 week growth window — with a 10-position adjustment range that accommodates neck sizes from 8 to 18 inches in a single collar purchase, eliminating the 3–4 collar upgrades typically required through puppyhood. The breakaway safety buckle releases under sustained pressure of 14 lbs, preventing strangulation if a puppy's collar catches on crate wire or kennel fencing during unsupervised play — the leading cause of collar-related puppy injury. A quick-release tab allows handlers to remove the collar with one hand during training sessions. Machine washable nylon webbing; available in 12 colors.
