The Australian Shepherd in numbers

An adult Australian Shepherd weighs 40–65 lb, which puts it in the medium size class. That gives a 36" crate, a chest girth around 22–28" and a neck around 14–18".

One of those numbers you can trust, three you cannot

Crate size really does follow weight, because it is set by the dog lying stretched out — the mapping from weight to the standard 18/24/30/36/42/48 inch sizes is the same at every manufacturer.

Girth is different. Two Australian Shepherds at the same weight can differ by three or four inches around the chest, depending on build, age and how much coat they carry. The range above tells you which size bracket to look in. It does not tell you your dog's measurement.

How to measure

Chest: around the deepest part, just behind the front legs, with the tape snug against the skin rather than the coat. Neck: where the collar sits, with two fingers underneath. Back: from the withers — the bump between the shoulder blades — to the base of the tail.

Measure standing, not sitting, and take it twice.

Notes

  • Australian Shepherd: Thick double coat — measure to the skin.
  • Girth and neck figures are the range this size class falls in, not a measurement of your dog. Two Australian Shepherds at the same weight can differ by three or four inches around the chest — put a tape on the dog before you order.
  • Crate size is the one number that does follow weight reliably, because it is set by the dog lying down stretched out. The dog should be able to stand without ducking and turn around without touching the sides.
