The Jack Russell Terrier is a small, tough and robust breed. A well-proportioned terrier usually weighs around 15 to 18 pounds and is 10 to 15 inches tall.
The double-coated Jack Russell Terrier has three varieties, namely broken, rough and smooth. The broken variety has an upper coat of varying lengths, or with longer hair on particular parts of the body. The rough coat has the top coat longer than the undercoat. Lastly, the smooth coat has a short, stiff outer coat. The coat colors of this breed are primarily white, with tan, black, or tricolor.
The active Jack Russell Terrier ideally requires two long walks or light jogs in one day. These hyperactive dogs are not only active outdoors, but also indoors. They would require plenty of stimulating activities when indoors as they tend to be irritable and destructive when bored. They should also be given the opportunity to play and run around while indoors for long periods of time.
This vocal breed is lively and bold. Jack Russell Terriers are generally playful, affectionate with family, and love attention. They need to have a job or training as a form of exercise. These highly energetic dogs tend to be highly excitable. But they do tend to be feisty with other dogs. Therefore, socialization and training must be done first before having them with other dogs.
Originally from England during the 19th century, the Jack Russell Terrier is very adept at digging burrows and trenches. They were named after hunting enthusiast Reverend John Russell, being the first person to breed them for fox hunting.
The three coat varieties of the Jack Russell Terrier are easy to care for. Regular combing and brushing with a firm bristle brush is required. Bathing should only be done when absolutely necessary. If these dogs are going to join the show ring, owners should ideally remove their fur.
The smart and intelligent Jack Russell Terrier is capable of picking up new skills and learning new tricks with ease. They respond very well to basic training, but can be difficult for the average dog owner to train.
The Jack Russell Terrier tends to be hyperactive to the extent that it becomes unmanageable. They need to be constantly trained throughout their formative years. Harsh, heavy-handed criticism should never be applied to the training of this breed, or any other breed of dog. It is recommended that the training be done in 2-3 daily sessions, being short and brief. Combine training with play and these dogs will respond very well.
The tough-looking Jack Russell Terrier is generally outgoing and enthusiastic in appearance. They are curious by nature. They are vocal, but never bark. This intrepid dog is very brave, which is why he seems to be unaware of his small size.
