When fully grown Jack Russell Terriers are 10 to 15 inches tall and weigh in at between 13 and 17 pounds.

Full grown Pugs are 10 to 13 inches tall and weigh between 14 and 20 pounds.

Because both the Jack Russell Terrier and Pug are about the same size, Jugs are about the size you would expect. They stand between 12 and 15 inches tall and weight between 13 and 20 pounds when they are full grown.

This is where owning a small dog saves money over other dogs as you will spend less money on dog food. As a rule of thumb, you should feed your adult dog 1 cup of food per day for every 15 to 20 pounds of body weight.

For most Jugs, this works out to one cup of dog food per day. It is best to spread it out over two separate meals throughout the day.

Due to their moderate shedding throughout the year, Jugs are not hypoallergenic dogs.

Do Jug Dogs Bark A Lot?

Jack Russell Terriers are a breed known to bark a lot. Pugs on the other hand are not known as barkers, but that may just be due to the fact that their bark is just not as loud.

Jugs seem to take their barking gene more from the Jack Russell. They are alert dogs that tend to bark when they hear noises and make great watch dogs.

Do Jug Dogs Have Health Issues?

For the most part, mixed breed dogs tend to be healthier than purebred dogs. Even though Jugs are relatively healthy dogs, all breeds have their own health issues.

Some health issues for Jug owners to watch out for are dry eyes, skin allergies, hip dysplasia, and respiratory issues. Jugs were originally bred to elongate the Pug nose to eliminate respiratory issues, but the effort has not been entirely successful.

If you have concerns about your Jug dog, be sure to seek professional veterinary advice.

Are Jug Dogs High Energy?

Jugs are generally medium energy dogs. While Jack Russells are an energetic breed and can be hyper dogs, Jugs also take a cue from their Pug heritage who are more calm dogs.

However, a Jug’s energy level will ultimately depend on if the individual dog is more like a Jack Russell or a Pug. It can be difficult to judge the exact energy level a Jug puppy will have as they get older, so if you are adopting a Jug you should be prepared for the possibility of a highly active dog.

If you choose to take your Jug into the water, it is a good idea to use a doggy life jacket.

Like all dogs, they need a strong pack leader (owner) to teach them right from wrong.

Are Jug Dogs Easy to Train?

Even though they can be stubborn, Jugs are definitely trainable. Like with any dog the keys to successful training are starting young, using positive reinforcement, and staying consistent.

Jugs are generally friendly dogs that get along with both people and other animals. Many Jugs inherit the Jack Russel hunting instinct. They always seem to be on alert and keep an ear out for any strange sounds.

Like their appearance, the personality of Jug dogs can also vary with some acting more like Jack Russells and others more like a Pug.

Do Jug Dogs Smell Bad?

All dogs have a certain “dog smell,” but Pug owners will tell you that Pugs can get pretty stinky. The main culprit is their skin folds that can trap dirt as well as more powerful scent emitting glands.

Mixed with a Jack Russell, the Pug smell is usually tampered down in the Jack Pug. The best way to reduce any dog smell is to take care of their coat with regular brushings.

Are Jug Dogs Recognized as Their Own Breed?

Because the breed is not a purebred dog, the Jack Russell Terrier Pug mix is not recognized as a breed by the American Kennel Club (AKC) or the UK Kennel Club.

Jug Dog Final Thoughts

Whether you call them a Jug, Jag, or Jack Pug, the Jack Russell Pug mix is an awesome dog breed. The Jug dog can make an excellent family pet that will even get along with other pets.

However, like all small dogs, they are not immune from small dog syndrome and so it is important to make sure they are trained and socialized early in their life.

The purebred Pug and Jack Russell Terrier are both popular dog breeds, so it’s no wonder that the Jack Russell Pug mix is becoming more popular as well.

If you are thinking about adopting a Jug puppy, I hope this post was able to answer some of your questions.
