Jack Russell Terrier and Miniature Dachshund
What both sides can say, then where they part, then what only one side can say, then what nobody has measured yet. A number without its sample does not appear.
Breed explains about 8.9% of the Morrill behavior factors in the paper. A bar here is a breed lean, never a prediction about a dog.
What they share
What cited lifespan means
How long dogs of this breed tend to live, from McMillan 2024 (VetCompass). A population median.
Where they differ
The numbers that speak do not pull apart.
One side known
Jack Russell Terrier: 12 lb (n=49) · Miniature Dachshund: 8 atlas dogs, no breed weight logged yet.
What typical adult weight means
Typical adult weight, in pounds.
Jack Russell Terrier: -0.7 years for size (n=49) · Miniature Dachshund: 8 atlas dogs, no lifespan-for-size logged yet.
What does longevity for its size mean?
How much longer or shorter a breed tends to live than its body size predicts (bigger dogs live shorter on average — this measures the gap from that expectation).
How to read it: Positive = lives longer than its size predicts; negative = shorter. At the extremes, roughly +3 years (longest-lived for its size) down to about -4 years.
A population pattern, not a guarantee for an individual dog.
Jack Russell Terrier: Border Terrier (n=49) · Miniature Dachshund: Not enough yet (n=8)
What genetic neighbors means
Where this breed sits among others in the atlas. Placement, not pedigree.
Jack Russell Terrier: 37% (n=49) · Miniature Dachshund: 32%
What does genetic diversity mean?
How varied a breed's gene pool is — the share of gene spots where a typical dog of the breed carries two different versions rather than two identical ones.
How to read it: Higher = more diverse. Among well-sampled breeds it ranges roughly 0.22 (least diverse) to 0.33 (most diverse).
Diversity is a strength, not a verdict on any individual dog. Lower diversity means it's worth paying attention to recessive-risk testing — not that a dog is doomed.
Jack Russell Terrier: -0.06 (n=27) · Miniature Dachshund: Not in the Morrill set.
What human sociability means
A breed lean on this factor in the Darwin's Ark paper. Not a prediction about a dog.
Jack Russell Terrier: -0.11 (n=28) · Miniature Dachshund: Not in the Morrill set.
What arousal level means
A breed lean on this factor in the Darwin's Ark paper. Not a prediction about a dog.
Jack Russell Terrier: -0.40 (n=29) · Miniature Dachshund: Not in the Morrill set.
What toy-directed motor patterns means
A breed lean on this factor in the Darwin's Ark paper. Not a prediction about a dog.
Jack Russell Terrier: 0.24 (n=33) · Miniature Dachshund: Not in the Morrill set.
What biddability means
A breed lean on this factor in the Darwin's Ark paper. Not a prediction about a dog.
Jack Russell Terrier: -0.06 (n=28) · Miniature Dachshund: Not in the Morrill set.
What agonistic threshold means
A breed lean on this factor in the Darwin's Ark paper. Not a prediction about a dog.
Jack Russell Terrier: -0.39 (n=33) · Miniature Dachshund: Not in the Morrill set.
What dog sociability means
A breed lean on this factor in the Darwin's Ark paper. Not a prediction about a dog.

What does carrier rate mean?
The share of tested dogs of a breed that carry at least one copy of a specific disease variant.
How to read it: Higher = more common in the breed. 'Carrier' means carrying the variant, not having the disease.
Carrier is NOT the same as affected, especially for recessive variants. Figures come from tested (direct-to-consumer) dogs, which can skew the rate. Worth asking your vet.
