Jack Russell Terrier History

Pug Jack Russell mixes come in many colors. They can also have white spots, though the chances are low because Pugs don’t carry the genes for white spotting.

Jug dogs’ coats are short and smooth. Crossbreds with a rough-coated Jack Russell parent can have broken coats.

The majority of Jack Russell Pug mixes are similar to Pugs. It is sometimes hard to tell the difference between them. The main difference is the length of their muzzle.

Jugs often have a dark face mask as both Pugs and Jack Russells carry the genes for this marking[5]. This feature is called a melanistic mask.

Health Problems From Pugs

Jack Russell pug mix dogs were bred to reduce some health issues that Pugs are prone to. Pugs are predisposed to several health problems due to their anatomy[7]. They are less healthy than many breeds.

Because of their anatomy, Pugs are prone to:[8]

  • Obesity 
  • Retained baby teeth
  • Corneal ulcerations[9]
  • Narrow nostrils
  • Allergies and skin disorders[10]

Jugs can inherit a predisposition to these diseases depending on how much they resemble Pugs. If they get their muzzle shape from pugs, they are less healthy.

Health Problems From Jack Russells

Jack Russells are healthy dogs but have a predisposition to certain diseases. Some of them are genetic, others are not. 

Certain genetic diseases in Jack Russells need both parents to carry the gene. This makes crossbreds less prone to these health issues. 

Common disease predispositions Jugs can inherit from Jack Russells:

  • Periodontal disease
  • Ear infections
  • Cushing’s disease
  • Patellar luxation

Patellar luxation is common to both Jack Russels and Pugs. This makes Jugs prone to this issue. 

Patellar luxation is a dislocation of the knee. It is common in many dogs[11]. Jug Puppies can have it also. Surgery can treat the problem.

What Is the Lifespan of a Jack Russell Pug?

How Much Do Jug Dogs Eat?

Jug dogs need a moderate amount of both dry and wet food. Split their daily amount of food into at least two meals. Adult Jug dogs need around 1 to 1.5 cups of food per day.

If your Jug inherits its energy levels from the Jack Russell parent, it needs a lot of food. This is why spreading their daily food amount into smaller meals during the day is essential.

Do Jugs Shed?

Yes, Jugs do shed, a trait they inherit from both parents. Jugs need daily brushing and regular bathing. This will keep hair off of your furniture.

Rare baths are recommended to reduce excessive shedding. The problem is Jugs are prone to skin infections. This is why you need to bathe them regularly but not too often. 

Too much bathing can lead to dryness. This results in excessive shedding and skin issues. A reduced number of baths can lead to skin infections. A balance is required when it comes to bathing.

Conclusion

Jack Russell Pug mixes inherit traits from both Jack Russell terriers and Pugs. Both breeds have a long history and have specific traits. The combination of these traits makes Jugs intelligent and agile. They are affectionate and vigilant at the same time.

Make sure to maintain an active lifestyle if you buy a Jug dog. They need moderate amounts of physical activity. They easily adjust to apartment living if you don’t skip their daily walks.
