what is the weight of a jack russell terrier
Jack Russell Terrier The Jack Russell should always appear balanced and alert.[32] As it is primarily a working terrier, its most important physical characteristic is its chest size, which must not be so large that it prevents the dog from entering and working in burrows.[16] The red fox is the traditional quarry of the Jack Russell terrier, so the working Jack Russell must be small enough to pursue it. Red foxes vary in size, but across the world, they average from 13–17 pounds (5.9–7.7 kg) in weight and have an average chest size of 12–14 inches (30–36 cm) at the widest part.[34]
Bull Terrier The Bull Terrier is a breed of dog in the terrier family. There is also a miniature version of this breed which is officially known as the Miniature Bull Terrier.
Jack Russell Terrier Jack Russells are an energetic breed that rely on a high level of exercise and stimulation and are relatively free from serious health complaints. Originating from dogs bred and used by Reverend John Russell in the early 19th century, from whom the breed takes its name, the Jack Russell has similar origins to the modern Fox terrier. It has gone through several changes over the years, corresponding to different use and breed standards set by kennel clubs. Recognition by kennel clubs for the Jack Russell breed has been opposed by the breed's parent societies – which resulted in the breeding and recognition of the Parson Russell terrier. Jack Russells have appeared many times in film, television, and print – with several historical dogs of note.
Jack Russell Terrier The breed has a reputation for being healthy with a long lifespan.[52][better source needed] Breeders have protected the gene pool, and direct in-line breeding has been prevented. Jack Russells can live from 13 to 16 years given proper care.[41] However, certain lines have been noted for having specific health concerns and, therefore, could occur in any line or generation because of recessive genes. These issues can include hereditary cataracts, ectopia lentis, congenital deafness, patellar luxation, ataxia, myasthenia gravis, Legg–Calvé–Perthes syndrome, and von Willebrand disease.[41]
