Basenji Breed Profile

Breed Overview

The Basenji is a small, elegant hunting dog that originates from Central Africa, where it was prized by local tribes for its speed, intelligence, and silent tracking abilities. Often referred to as the “barkless dog,” the Basenji doesn’t bark like other breeds but makes unique vocalizations known as “yodels” or “baroos.” This breed is highly independent, curious, clean (often likened to a cat), and requires mental stimulation and regular exercise.

Classified as a small breed, the Basenji typically weighs between 20 and 26 pounds at maturity and stands approximately 16 to 17 inches tall. Though small, growth tracking is important to ensure healthy skeletal development, especially given their lean build and high activity levels. Accurate monitoring helps prevent issues like underfeeding, obesity, and orthopedic stress.

Basenji Growth Chart & Weight Ranges

The following table outlines average weight ranges for Basenji puppies by age. Males usually weigh 3–5 lbs more than females at full maturity.

Age	Average Male Weight	Average Female Weight
4 weeks	2 – 3.5 lbs	1.5 – 3 lbs
8 weeks	5 – 7 lbs	4 – 6 lbs
3 months	8 – 11 lbs	7 – 10 lbs
4 months	10 – 13 lbs	9 – 12 lbs
6 months	14 – 18 lbs	13 – 17 lbs
9 months	17 – 22 lbs	16 – 20 lbs
12 months	20 – 26 lbs	18 – 24 lbs

Most Basenjis reach their full adult weight and height by 12 months, although some may continue to gain muscle tone until 14–16 months.

How Much Bigger Will My Basenji Puppy Get?

Basenjis experience steady growth during their first year:

• By four months, most puppies have reached approximately 50–55% of their adult weight.
• A useful rule of thumb is to double their weight at 16 weeks to get a rough estimate of their adult size.
• Unlike large or giant breeds, Basenjis usually reach their full adult size by 12 months, with minimal changes after that point.

Because Basenjis are lean and muscular by nature, it’s important not to confuse slimness with underweight — their ribs may be slightly visible even at a healthy weight.

Basenji Growth Tips

Nutrition

• Feed a small-breed puppy formula that supports active metabolism and lean muscle development.
• Offer 3 meals per day until 6 months of age, then reduce to 2 meals daily.
• Avoid overfeeding or excessive treats — Basenjis are naturally slender, and extra weight can impact joint health and energy levels.

Ensure the food meets AAFCO standards for growth in small breeds and contains quality protein sources.

Exercise

• Basenjis need daily physical and mental stimulation:
  • Engage in short walks, play sessions, and puzzle toys.
  • Avoid strenuous running or jumping before 6–8 months to protect developing joints.
  • A secure, fenced area is ideal—Basenjis are known for their agility and escape skills.

Health Watch

Basenjis are generally healthy, but here are some growth-related concerns to monitor:

• Hip dysplasia – while not common in small breeds, it can occur.
• Fanconi syndrome – a genetic kidney disorder that may emerge in adulthood; early signs include poor weight gain or drinking/urinating excessively.
• Obesity – keep close track of weight, especially after neutering/spaying.

Routine vet visits, a structured feeding plan, and controlled exercise help your Basenji grow into a healthy and active adult—ready to explore, play, and stay curious.
