When is my Australian Shepherd an adult?

As an old and established breed, Australian Shepherds are generally relatively standardized when it comes to size. There are, however, notable differences between men and women. Australian boys are typically 20 to 23 inches and 50 to 65 pounds, while girls are 18 to 21 inches and 40 to 55 pounds.

A recent trend in the search for smaller versions of distinctive dogs has led to the creation of a smaller version of the Australian Shepherd, which the AKC distinguishes from the Australian by calling it the Miniature American Shepherd. These cute little dogs stand from 13 to 18 inches tall and weigh from 20 to 40 pounds, but they are equal to Australian Shepherds in almost every other way.

Australian Shepherd Growth Timeline

Growth charts and timelines can be invaluable and I know many owners want to know how much their puppy should weigh at a certain age.

Side note: Although these graphs can give you a good idea of ​​where your pup «should» be, don’t panic if your pup doesn’t match. I know people who made unnecessary vet appointments simply because their pup didn’t exactly match a chart they saw online. Some puppies grow slower or faster than others, and this depends on a few factors that I explain later.
