Dog Collar for Mastiffs Buyer’s Guide

Choosing the right collar for your Mastiff is an important decision.  It needs to be strong and durable, but lightweight and comfortable.  A premium collar to fit your Mastiff’s large, powerful neck may be more expensive, but it is worth the investment for peace of mind.  A cheap collar can fray, break or hurt your dog.  Always measure your Mastiff’s neck properly and carefully follow the manufacturer’s recommended sizes.

Our buying guide reviews the best dog collar for Mastiffs on the market so you can choose the right collar for your Mastiff.  The following considerations should be made and will help you to choose which collar you need for your dog.

Length and Width

In general, you should add about three inches to your dog’s neck measurement when choosing a collar.  This means most Mastiffs will fit a collar somewhere between about 24 to 30 inches long.  Always follow the two-finger rule, where you can comfortably fit two fingers between the collar and your dog’s neck.  Your Mastiff needs a good, wide collar as well.  The width is for his comfort, but also his safety to prevent damage with a collar that is too narrow.  Be sure to choose a collar that at least 1.5 inches in width.


The most common material for large-size dogs is heavy-duty nylon with double stitching.  A more premium collar would be leather, which is super durable and comfortable with inner padding.  Many collars for Mastiffs are lined with a soft neoprene padding to prevent chafing. It’s important to consider the buckles as well.  Any plastic buckles should be made with high-quality plastic.  Metal or steel hardware is an option as well for higher durability.  A plastic/metal hybrid buckle offers extra security for your Mastiff but as with all buckles, should still be quick-release.
