When Does a Smooth Fox Terrier Stop Growing?

Smooth Fox Terriers typically reach their full adult height of 14–15 inches by 12 to 15 months and their full adult weight of 15–18 lbs shortly after. Elegant and athletic at 15 to 18 pounds and up to 15.5 inches tall, they should be well-balanced and symmetrical with a short back..

Factors that influence growth include genetics, nutrition, and spay/neuter timing. Dogs spayed or neutered very early may grow slightly taller due to delayed growth plate closure.

Is My Smooth Fox Terrier Overweight?

To determine if your Smooth Fox Terrier is at a healthy weight (15–18 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 Smooth Fox Terrier is overweight, work with your veterinarian to develop a safe weight loss plan. Even a 10% reduction can reduce the risk of Lens Luxation and other conditions.

Adult Smooth Fox Terriers (15–18 lbs) typically need 0.5 to 0.4 cups of high-quality dry food per day, divided into two meals. A formula suited to small breeds provides appropriate nutrient density. Demand at least 60 to 90 minutes of vigorous daily exercise, excelling in agility, flyball, and barn hunt, with their prey drive requiring secure fencing.—adjust portions based on activity level. Budget $39–62/month for food costs.
