When Do Dogs Stop Growing?

family-footerIf you recently adopted a puppy, you may be curious to know when he will stop growing. Besides satisfying your curiosity, it’s important to recognize when your dog is fully grown, so you know when to invest in that expensive collar, harness, or dog bed without fear of your pup outgrowing it. If you rescued your dog from an animal shelter, you can also better predict his age if you know when his particular breed stops growing. This guide can help.

When Small Breed Dogs Stop Growing

Also called toy breeds, Chihuahuas, Yorkshire Terriers, Toy Poodles, Dachshunds, Miniature Pinchers, and other small breed dogs mature the fastest. This makes sense, considering that toy breeds max out at just 4 to 12 lbs.

With a healthy diet, you can expect your small breed dog to be fully grown at eight to 12 months old. During this time, your dog will also grow his adult coat, reach his full weight, and mature sexually and emotionally.

When Medium Breed Dogs Stop Growing

Bulldogs, Shetland Sheepdogs, Corgis, Standard Schnauzers, Whippets, and other medium breed dogs weighing about 25 to 50 lbs also finish growing within the eight- to 12-month range. Since they end up larger than their small breed cousins, it’s vital to provide your pup with the proper nutrition to ensure he reaches a healthy size and weight in the expected timeframe.

When Large Breed Dogs Stop Growing

Weighing in at 50 to 100 lbs, large breeds such as German Shepherds, Labrador Retrievers, Siberian Huskies, Collies, and Dalmatians take longer to reach their full size. Expect your large breed dog to finish growing at about 10 to 16 months old. Some breeds continue to fill out past the 16-month mark, but they should reach their full height within this range. Give particular attention to your large breed dog’s diet, as growing too quickly could be detrimental to your puppy’s health.

When Giant Breed Dogs Stop Growing

The giant breeds—including Saint Bernards, Great Danes, Newfoundlands, Mastiffs, and Irish Wolfhounds—reach 100 to 200 lbs or more once fully grown. As with their slightly smaller large breed cousins, giant breed dogs require specific diets to prevent overly fast growth during puppyhood that could damage their health.

Expect your giant breed dog to finish growing by 16 to 18 months of age at the latest. Make regular vet visits a priority to learn how to raise a happy, healthy giant breed dog since their needs often differ from smaller breeds.
