Pounds. The dark band is where most Lab Jack Russell Mix dogs end up; the light band is the full range between the smallest and largest parent.

Height runs 17–19 inches at the shoulder, against 21.5–24.5 in for the Labrador Retriever and 13–14 in for the Jack Russell Terrier. The parents differ a lot in size, so litters vary more than usual. Breeders normally use the larger breed as the mother to keep whelping safe.

Figures use the Parson Russell Terrier standard, the AKC breed closest to the Jack Russell.

Coat, energy and training

Shedding

Low to high

Neither parent has a low-shedding coat, so expect dog hair around the house and seasonal heavy shedding.

Energy

Very high

Plan on long daily walks plus real exercise, such as running, fetch or a sport. A yard alone will not tire this dog out.

Trainability

Moderate to very high

The Labrador Retriever rates very high and the Jack Russell Terrier moderate; a puppy may lean either way.

Grooming

Low

A weekly brush and the odd bath keep the coat in shape.

Temperament

The Labrador Retriever is usually described as friendly, active, outgoing. The Jack Russell Terrier as friendly, clever, athletic. A mix can take after either parent or land in between. If you can, meet both parents of a puppy before you choose.
