Growth Chart

When Does a Working Kelpie Stop Growing?

Expect your Working Kelpie to reach adult height of 15–20 inches by 12–15 months. Full body maturity—including muscle development toward the 25–46 lb target—may continue until 14–18 months.

Growth is influenced by genetics, nutrition quality, and spay/neuter timing. Cerebellar abiotrophy is the key breed-specific concern, a progressive neurological disorder. DNA testing is available and should be mandatory for breeding stock. Generally very healthy due to working selection..

Is My Working Kelpie Overweight?

To determine if your Working Kelpie is at a healthy weight (25–46 lbs target):

  • Rib test: You should be able to feel the ribs without pressing hard, with a thin layer of fat covering them
  • Waist check: Viewed from above, there should be a visible waist behind the ribs
  • Tuck-up: From the side, the abdomen should tuck up behind the rib cage

Their coat type allows for relatively easy visual assessment. If your Working Kelpie is overweight, work with your veterinarian to develop a safe weight loss plan. Even a 10% reduction can reduce the risk of Cerebellar Abiotrophy and other conditions.

Feeding Recommendation

An adult Working Kelpie's daily food intake is typically 0.5–0.9 cups of high-quality kibble, fed in two meals. Both sexes weigh 25 to 45 pounds. They should appear lean, muscular, and athletic. Any excess weight reduces their working efficiency. The breed standard prioritizes function over specific size requirements.. At 25–46 lbs with energy level 5/5, Cerebellar abiotrophy is the key breed-specific concern, a progressive neurological disorder. DNA testing is available and should be mandatory for breeding stock. Generally very healthy due to working selection..

(3) Side profile–the abdomen should tuck up. Target weight: 25–46 lbs. Their coat type allows for relatively easy visual body condition assessment. Consult your vet for a body condition score.
A Working Kelpie puppy growing toward 25–46 lbs needs carefully measured portions. Feed 3–4 times daily until 6 months, then twice daily. As a herding breed with energy level 5/5, active puppies may need portions at the higher end of guidelines. Monitor body condition weekly and adjust as needed.
If your Working Kelpie puppy isn't gaining weight as expected (target adult weight: 25–46 lbs), consult your vet. Common causes include intestinal parasites, insufficient calorie intake, or malabsorption. The breed's predisposition to Cerebellar Abiotrophy could also be a factor worth investigating. A fecal test and blood work are typically the first diagnostic steps.
