How much should an adult Basenji weigh?

The Kennel Club breed standard puts an adult male Basenji at around 11kg and a female at roughly 9.5kg, with a height of about 40 to 43cm at the shoulder. Individual dogs vary either side of this within a normal, healthy range.

At what age is a Basenji fully grown?

Most Basenjis reach close to their adult height within the first year, with continued filling out in muscle and condition up to around eighteen months to two years old, which is typical timing for a medium-sized athletic breed.

Are Basenjis supposed to look thin?

Yes, to an extent — Basenjis are a naturally lean, lightly built hound breed, and a visible waist with a tuck towards the back legs is normal even at a healthy weight. If you are unsure whether your dog's build is healthy or genuinely underweight, your vet can check their body condition properly.

Basenji weight chart

The Basenji is a lightly built, athletic hound, and the Kennel Club breed standard puts an adult male at around 11kg and a female slightly lighter, at roughly 9.5kg, with a height of around 40 to 43cm at the shoulder — a useful landmark, though it cannot substitute for looking at your own dog's condition.

What a weight chart can and cannot tell you

A breed chart gives a range most healthy adults of that breed tend to fall within, which is a reasonable check if your dog looks noticeably outside the expected size for their age. It cannot judge an individual dog's frame or muscle, which is why two Basenjis at the same weight can look quite different depending on how lean or well-muscled they are.

Basenjis are naturally a lean-looking breed by build, with visible waist and a light frame even at a healthy weight, so do not expect the same silhouette you might see on a stockier breed — lean is normal here, not a sign of being underweight.

Tracking growth against the breed's pace

Basenjis generally reach most of their adult height within the first year, with some continued filling out in muscle tone through to around eighteen months to two years, which is typical for a medium-sized, athletic hound breed. Comparing your dog's weight to the breed standard is fairest once they are close to full maturity rather than while still a young puppy.

If you are tracking growth, weigh at a similar time each week or fortnight and look at the overall trend, since a single reading can be thrown off by things like how recently your dog last ate or toileted.

Judging condition rather than the number alone

For a lean breed like the Basenji, body condition is arguably more useful than the number on the scale. You should still be able to feel the ribs without pressing hard, and there should be a clear waist and a visible tuck up towards the back legs, which is a normal feature of the breed's build rather than a sign of being too thin.

If your Basenji looks unusually heavy for the breed, is gaining weight steadily without a change in diet or exercise, or sits well outside the typical range for their age, that is worth raising with your vet, who can assess your individual dog rather than compare them to a general figure.
