The Jug is the intentional cross between an ancient and well-known lap dog, the Pug, and a tireless fox hunter that was developed by a breeder by the name of John “Jack” Russell in Devonshire, England in the early 1800s. The two breeds differ a great deal in appearance, structure, and temperament, so their offspring may vary quite a bit between individuals, even within the same litter. This hybrid may or may not do well in an apartment; those that lean towards the quiet and sedate behavior of the Pug will generally do quite well, however, those that take after the Jack Russell are more likely to be both too active and too vocal to make a good neighbor.

Jug Breed History

 

The Jug is a popular designer dog that has been in development since the 1960s, an intentional crossbreed between the Jack Russell Terrier, an energetic and enthusiastic fox hunting dog developed in England, and the Pug, an ancient lapdog that was favored in China for thousands of years. The Pug is actually believed to be one of the oldest dog breeds on record and the dogs have been considered prized possessions by Chinese Emperors since the Shang dynasty, around 1600 BCE. Like many other dogs that were valued by royalty, Pug puppies were often given as gifts to visiting royal families and other dignitaries and in this way were distributed throughout the world. The Pug became particularly popular with the royal family in 19th century England, where they gained favor with Queen Victoria who’s involvement with this and other breeds led to the establishment of the Kennel Club in 1873. The Pug breed was also one of the first 15 breeds to be recognized by the American Kennel Club when they were first established in 1885. The Jack Russell Terrier, also known as the Parson’s Jack Russell Terrier, is a much more recently established breed than the Pug, developed by a man named John Russell, a parson and breeder of foxhounds in Devonshire, England. Originally inspired by a single female of undetermined parentage that Mr. Russell bought from a milkman in 1819, the Jack Russell Terrier was developed to be both tall enough to keep up with the foxhounds and small enough to go to ground if the fox retreated to their dens. Unlike many other terriers, the Jack Russell Terrier was bred to chase the fox without capturing or killing it. The Jug is typically less high-strung and hyperactive than the Jack Russell Terrier and has fewer breathing problems than the purebred Pug. 

Jug Breed Appearance

Although the Jack Russell Terrier and the Pug are similar in size, they are very different in appearance, temperament, and in purpose, so there can be quite a bit of variation from dog to dog with this crossbreed, even within the same litter. In most cases, the Jug is a heftier animal than the Jack Russell, but not quite so stocky as the Pug. The head is generally broad and the muzzle can range anywhere from the short, blunt muzzle of the Pug to the more elongated and tapered muzzle of the Jack Russell. The coat can vary somewhat from dog to dog as well, depending mostly on the type of Jack Russell that was used in the crossbreed, the smooth, broken, or rough-coated Jack Russell. The most commonly seen coat for the Jug is either a single or double layer coat characterized by short, glossy fur, similar to the coat of the Pug or of the smooth-coated Jack Russell Terrier, however the longer or rougher coat of the broken or the rough coated Jack Russell may also emerge.

Jug Breed Maintenance

The Jug is typically an easy animal to groom. They require only occasional bathing and the short, neat coat that is most commonly seen can be maintained simply by brushing the dog once or twice a week with a bristle or slicker brush. Although mats are less likely with short coats, regular brushing helps to remove dead hair and to properly distribute the dog’s natural oils, keeping their coat shiny and supple. Dogs that inherit the broken or rough coat from the Jack Russell will typically require more brushing, both in the duration and number of sessions. This particular crossbreed may also be more prone to dental disease than other dogs, so regular tooth brushing and dental visits may both improve and extend this hybrid’s life.

Jug Temperament

The Jack Russell Terrier is an extremely intense working dog with a strong prey drive and a great deal of energy. The Pug, on the other hand, is a calm, affectionate, and somewhat clownish individual whose main purpose in life is just to be with you. This trait, combined with their intelligence, makes them an easily trainable animal, although they can exhibit mischievous or destructive behaviors if they become bored or anxious. In most cases, this crossbreeding results in a brave and energetic canine that also has a sociable and loving nature. The high prey drive of the terrier is rarely extinguished in this hybrid, and in most situations, this dog should not be trusted off leash nor should it be left outside alone as the temptation to chase squirrels and other small animals may prove to be impossible for your Jug to resist. If properly socialized, the Jug is pleasant and affectionate towards all ages and towards other animals, provided it can resist their powerful urge to chase anything that runs. If not socialized, these dogs may be oversensitive to stimuli and can develop jealous, stubborn, or obsessive behaviors. 

Jug Activity Requirements

The Jack Russell Terrier tends to be an extremely active little dog, but the Pug tends to be a more sedate, sometimes even lazy, canine. While a hybrid animal can end up with activity requirements on either side of the spectrum, the most common outcome ends up somewhere between the two, resulting in an energetic animal, but not a hyperactive one. Ensuring that your Jug gets at least 45 minutes to an hour of vigorous exercise each day is generally sufficient to keep this dog healthy and fit, although breaking it up into two or three shorter exercise sessions will be more beneficial than exercising for the full time just once a day. Dogs that have shortened muzzles are also at higher risk of developing problems due to overheating and should not be overtaxed when the weather is warm.

Lenny is a sociable and loving dog. He loves his walks and was really easy to train! He was attacked at a young age by a Labrador so he’s a bit wary of big dogs but other than that he is lovely!

He is very affectionate and energetic. He loves to cuddle and play. He enjoys swimming. When he was younger he loved playing in the snow but now that he is older he seems to get cold quickly and a bit more separation anxiety. He doesn't bother much with other dogs but enjoys playing with humans more. He is completely obsessed with rubber balls. He is very intelligent and easily trainable. He likes to drink a lot of water and pee a lot in the day time, however, at night he can go 10 hours without either. He loves sleeping in; especially on our bed!

He did very well in an apartment when we lived in one. We recently moved to a house with a big back yard and it's been tough for us because he gets fixated on the rabbits that he sees in our yard. His Jack Russell traits have really come through; he's very healthy and pretty low maintenance but he will take off after birds, squirrels, or any critter in the yard and he's a VERY fast runner. An extremely loyal dog, he LOVES his humans and our immediate family, but he's unsure of strangers. Not the slightest bit aggressive. Will bark at strangers in our home but will never go after them. Strangers anywhere else will usually get ignored, unless they have a treat. Loves his cat sister, and is very affectionate. Because of his JR tendencies, he must have some sort of activity per day, otherwise he becomes very needy and will demand attention. 30 solid minutes of moderate activity will guarantee a long nap afterward. Health is good, but he has a major sensitivity to corn and will get sick to his stomach if he ingests it. Very sensitive stomach overall and will get really bad and stinky gas if he eats something that doesn't agree with him. We've figured out the best formulas for him and he is very happy and healthy. Must give him glandex daily due to a history of anal gland issues, which is common with terriers and pugs.

This is my first dog on my own and he is the absolute best!! i couldn’t have gotten a better breed. He loves cuddling but also loves to come to work with me at a doggy daycare. Otis gets along with all dogs, big and small, but he seems to want to play with the bigger ones more often! he absolutely loves when other dogs chase him, and he’s always the fastest one in the group!! highly recommend this breed.

IMPOSSIBLE to train my dog. Can not potty train her. Treats do not work. Positive reinforcement is wasted on her. I take her to her "potty spot" and she won't go. I walk her around the block and she won't go. As soon as we walk in the house, she sh*ts on the couch. Literally can't leave her alone. She is very attached to me. Loving creature and very playful. High energy levels. But I struggle with training. Crate training doesn't work either. She pees in her crate, even when walked every 30 minutes. Not sure what else to try but I am moving out in a few months and I can't have her going inside the new apartment.

Digit was found as a stray. He was very scared and anxious around everyone, except other dogs. We have a Pit/Husky as well and they’re best buddies. Constant socialization and lots of hikes helped Dogit gain confidence. Now he’s a champion and loves just about everyone!

Jax is right in the middle of the Spectrum of his genes. He's both lazy and playful. He spend 8.5 hours a day alone and is house trained. Very RARELY does he have an accident. He plays well with the two cats (One likes him one doesn't) He is extremely intelligent. I live in a small village with a fairly decent sized yard and he runs free and never leaves the property. When we go for walks he is leashed (no leash while hiking) He listens well. He is very alert, barks when someone pulls in the driveway or comes to the door - stops barking when I tell him "enough". I didn't get him neutered until 18 months and he did seem to calm down, lean more towards the Pug breed. He gets along well with other dogs. He drives me nutts at times but he's my best friend

As a puppy she was super active and loved to play with toys and she also would get bored easily and start chewing on things she wasn't supposed to. When Molly hit around age 3 she wasn't so interested and toys and she just wanted to go outside play, eat, and sleep. Now that she is 6 she loves just cuddling with us all day and she is well tempered. She loves meeting new people and she is really good at watching little ones.
