Patterdale Terrier cross Jack Russell

The Patterdale Terrier cross Jack Russell, also referred to as a Patterjack, is a wonderful crossbreed; if trained and looked after correctly, they will make a best friend for life. 

The Patterjack is a lovable, strong-willed dog with a brilliant personality. A mixture of two terrier breeds, the Patterjack is full of energy and can be a challenging dog for inexperienced, first-time owners. 

So, how did the Patterjack come about? 

Crossbreeding of dogs has existed for many, many years. It’s the process of breeding two separate breeds together to fulfil a specific need or desire. 

Take the extremely popular Cockapoo, for example. This Cocker Spaniel Poodle mix was originally bred to fulfil a need for hypoallergenic dog breeds that wouldn’t trigger allergies.

The main reason for crossbreeding the Patterdale Terrier with a Jack Russell Terrier was their size. By mixing the taller, long-legged Patterdale with the shorter, sturdier Jack Russell, the resulting crossbreed would be a balance between the two. 

The history of the Patterjack

Unfortunately, the origin of the Patterjack is somewhat undocumented, with no records of their first appearance. However, the Jack Russell Terrier has been around since the 1800s, while the Patterdale has been around for over a hundred years. 

The Patterdales were later popularised during the 1950s-1960s. Using this information, we could assume that the earliest Patterjacks would have been bred would be anywhere between the 1920s and the 1960s. 

Why breed the Patterdale with a Jack Russell? 

To better understand the crossbreed, it’s important to first look at the parent breeds and their history. 

Parson John Russell bred the Jack Russell Terrier back in the 1800s. He wanted to develop a dog breed that could keep up with the hounds typically used during hunts yet be small enough to enter into dens and burrows to finish the job. 

Their smaller size made them ideal for fitting into small gaps, and their terrier nature meant they could easily keep up with the hounds during a chase. 

Parson John Russell successfully achieved his goal; the Jack Russell Terrier soon became a favourite of hunters across the UK and the US.

A descendant of the Fell Terrier, the Patterdale Terrier originates from Northern England. Here the Patterdales fulfilled their purpose; dispatching foxes during hunts and controlling vermin on farms. 

Mixing the Jack Russell with the Patterdale was primarily done in order to achieve a dog breed with an average size between the two. By breeding these two together, you could benefit from a terrier with a high prey drive that could hunt a broader range of animals due to its height.

Let’s take a closer look at the individual breeds and their characteristics…

Jack Russell Terrier

Russell Terrier

The Jack Russell is a working terrier breed through and through, initially bred by Parson John Russell, who was passionate about fox hunting. 

Overall the Jack Russell is a quick and reliable breed with a high prey drive and tonnes of energy. Although originally bred only for hunting, the Jack Russell is still a popular dog breed today; their quirky personalities make them brilliant companions. 


The popularity of the Jack Russell Terrier may be attributed to its affordable price. On average, you can purchase a Jack Russell Terrier puppy for around £500, while some breeders advertise them for up to £1000. 

Adult Jack Russell Terriers can be purchased for as little as £200. However, you should always be apprehensive when dogs are advertised for a price that seems too good to be true. 


The Jack Russell Terrier breed is incredibly broad. Although the Kennel Club recognises them, their breed standard isn’t strictly adhered to by all breeders.

Traditional Jack Russell Terriers should be at least 51% white with black or tan coloured markings and patches. However, it is also common to see Jack Russell Terriers predominantly black in colour with white and tan markings.

Hair type

Jack Russell Terriers typically come in three different coat types: smooth, broken or rough. 

The smooth coat is short in length, straight and relatively coarse, with a thick undercoat. In contrast, the rough coat is much longer and wiry to the touch, also with a dense undercoat. 

The broken coat is a mixture of the two, sitting somewhere between smooth and rough. Usually, Jack Russells with a broken coat will have a stripe down the middle of their backs, as well as feathering around their face and legs. 


The Jack Russell Terrier requires minimal grooming as a general rule of thumb. The smooth and broken coated varieties should be brushed once a week/fortnight, while the rough-coated Jack Russell may require more frequent brushing. 

A Jack Russell will naturally wear their nails down with their active lifestyle; however, it’s a good idea to check them regularly and trim them if necessary. 

Some Jack Russells will develop issues with their teeth, particularly plaque build-up. Regular brushing or dental chews can help to prevent this issue.

Patterdale Terrier

Patterdale Terrier

The Patterdale Terrier has a similar background to the Jack Russell Terrier. Patterdales are also working dogs, initially bred for hunting foxes and rodents. 

They are a definite terrier breed; energetic, with a strong prey drive, highly intelligent and particularly stubborn!


Patterdale Terrier puppies typically sell for anywhere between £500-£800 – a similar price to the Jack Russell Terrier. 

If you’re after an adult Patterdale, you’re looking at the cost of around £200-£400, depending on the reason the current owner put them up for sale.


Patterdale Terriers are less varied than Jack Russells in appearance. You will commonly only see Patterdale with a black or a chocolate-coloured coat.

Some Patterdale Terriers have white markings on their coats, particularly around their faces; however, a consistent and uniform appearance is more common.

Hair type

Just like the Jack Russell Terrier, the Patterdale also comes in three different coat types: smooth, rough and broken.

Similarly to the Jack Russell Terrier, Patterdales often have extra fur around their faces that can sometimes make them appear to have a beard.


The Patterdale Terrier is a relatively low-maintenance dog due to its short hair. As a result, they only require a brush around once a fortnight if possible.

Unless you’ve been on a particularly muddy walk or your Patterdale enjoys digging in the garden, you will only have to bathe them on average every 10-12 weeks.

Their nails may need clipping, so pay attention to them; however, they are usually incredibly active, meaning they will wear them down naturally on the ground.

Now we have a better understanding of both the Patterdale Terrier and the Jack Russell Terrier, let’s take a look at the resulting mix: the Patterjack.


Overall, the Patterjack is a great looking dog. They are usually of a muscular build, which, combined with their short height of around 12-14 inches, can make them appear rather stocky.

They have long but floppy ears that will almost reach their eyes when folded over. Patterjacks have dark eyes and either a black or brown coloured nose. 

Their short, muscular legs, upright tail and deep chest give them an alert, authoritative appearance commonly associated with a Terrier breed.

A Patterjack’s fur can be a range of colours, including black, white, brown, red, sable and brindle. Either they are entirely made up of one shade or a combination of two with patches across the body. 


The Patterjack is a stereotypical terrier. They have an extremely high prey drive, and they will chase after small animals. So, be careful walking your Patterjack off lead around wild animals like rabbits. 

They may also chase cats; however, it is possible to own both a cat and a Patterjack if they have been brought up together from a young age. Having a Patterjack in the same home as smaller pets like hamsters and guinea pigs is not recommended due to their prey drive.

They make great family dogs, as they usually get on well with children. However, please be wary as the Patterjack doesn’t have a great deal of patience and won’t tolerate being mistreated!

Overall, the Patterjack is hard-working, clever and always ready to go. However, they require strong leadership, so it’s essential to train them properly and be firm with them when necessary. 

Exercising a Patterjack

When it comes to Patterjacks, exercise is critical. As a terrier breed, they are full of energy and require high levels of activity to tire them out. Therefore, multiple walks a day and off-lead runs during the week are ideal.

As well as physical exercise, Patterjacks also require mental stimulation. Being a working dog breed, the Patterjack craves tasks, making training and agility work ideal.

Puzzles and games are also good to tire them out. For example, hide treats around the house and let them use their nose to find them. 

There are lots of puzzles and games created for dogs like Patterjacks available on the market, so try them out and see what works for you.


The Patterdale Terrier and the Jack Russell Terrier are relatively affordable dog breeds, and the Patterjack is no different.

Patterjack puppies cost on average between £500-£800 – a similar price to the individual breeds. However, as usual, adult Patterjacks are less expensive than their younger versions and are available for as little as £200 up to £400. 

Overall the Patterjack is an excellent breed; highly intelligent, caring and affectionate, and always up for anything. With proper training and care, the Patterjack makes a companion for life – and all for an affordable price!
