The Jack Russell Terrier is a small-sized breed. Males typically weigh between 6 and 8 kg when fully grown, while females weigh 5 to 7 kg. With an average lifespan of 13 to 16 years, the Jack Russell Terrier is a long-lived breed.
Jack Russells are fearless, energetic, and intelligent terriers with an intense prey drive. They are lively, independent thinkers who can be challenging for first-time owners. JRTs are loyal and affectionate with their families but can be feisty with other dogs. They are vocal dogs who will alert to anything unusual. Their intelligence and energy make them excel in agility and other dog sports.
Jack Russells have high exercise needs despite their small size — at least 1-2 hours daily. They love running, digging, chasing, and playing fetch. They need both physical and mental stimulation. A bored Jack Russell is a destructive Jack Russell. Secure fencing is essential as they are expert escape artists who can jump surprisingly high.
Common health concerns include patellar luxation, Legg-Calve-Perthes disease, deafness, eye conditions (lens luxation, cataracts), and spinocerebellar ataxia. They are generally a healthy, long-lived breed. Their high energy and fearless nature can lead to injuries from jumping and rough play.
Jack Russells come in smooth, broken, and rough coat varieties. All types shed and benefit from weekly brushing. Rough and broken coats may need hand-stripping. They are relatively low-maintenance grooming-wise. Regular nail trimming and dental care are important.
