Will My Puppyâs Harness & Collar Fit When Theyâre Full Grown?
By Editor
If youâre about to adopt a puppy, you probably have half a billion questions. Today, weâre answering one of the questions we hear most often from our customers: Will my puppyâs Freedom Harness or new collar fit when theyâre full grown? We know that buying a stylish dog collar or harness is an investment, and making it fit as long as possible may be financially appealing. However, even adjustable collars or harnesses wonât fit your dog once theyâre full grown - and you shouldnât continue to use them once they start to fit poorly or if they have been chewed (but we have a Chewing Warranty for the Freedom Harness!) Read on to learn why your puppyâs harness or collar wonât fit once theyâre full grown, and why you should replace them as often as needed.
Puppies grow quickly, and for some larger breeds, your dog may take up to 12-24 months to reach their full adult size. If you adopt a 30-pound German Shepherd, your dog could gain 30+ pounds in less than a year. Even if you buy an adjustable collar or harness and move them to their largest settings, those items wonât fit comfortably or safely as your dog continues to grow. To make sure your dog is safe at all stages of their growth period, check the fit of their collar and harness every few weeks. Use our sizing chart to understand when itâs time to purchase a bigger set.
Having a collar or harness fit for as long as possible sounds great budget-wise, but using the same collar or harness for years on end may not be the safest option for your growing dog. Most puppies chew at least a little, and some of the most commonly chewed items include collars and harnesses. If your pup is chewing their collar or harness, itâs time to replace it. Even small bites taken out of the material can damage the harnessâs ability to keep your dog safe.
Puppies Grow Quickly

Dogsâ Proportions Change
Even if you adopt a smaller breed, puppiesâ proportions change quite a bit as they grow. If your puppy wonât get much taller, theyâll likely gain girth, especially in their chest area. The size of your dogâs neck and chest dictate the size of collar and harness they should be using, so as your dog grows, so too should these items.Theyâll Experience Wear & Tear

Theyâll Lose Elasticity
Even if your pup doesnât chew their collar or harness, over time, these items begin to lose elasticity. If your dogâs collar and harness is starting to lose its shape, try washing it to see if it will return its integrity. If it doesnât, itâs time to buy a new set.Your Dog Changes As He Grows
