Let’s get started.

Jack Russel Terriers are an active, energetic breed that has an instinctive desire to hunt and play games such as chasing and throwing balls along with vigorous jumping capability.

They are best suited for families wanting a dog that is loving, playful yet tough enough to hunt vermin, dig holes or jump through yards.

The Jack Russell Terrier is a dog that needs physical activities such as daily walks, frequent games of fetch, and games of tug-of-war. What it really likes is to be able to chase on a leash or go for a run with you.

In addition, they enjoy training sessions where they perform tricks or jump over obstacles. If you have an active lifestyle and are able to keep up with their need for exercise, then it would be best for you to adopt a Jack Russell Terrier.

Health & Life Span

The Jack Russell Terrier can live between 13-16 years (varies by size) while sometimes reaching their 17th birthday. As with all dogs, getting the proper care is vital as it will help your dog live a longer healthier, and happier life.

This breed doesn’t tend to inherit any specific health problems but can be prone to hip dysplasia. As with any dog, access to outdoor space is important as it reduces the risk of arthritis and obesity which may shorten your Jack Russell Terrier’s lifespan.

The Jack Russell Terrier is a very active and energetic breed. It would do best in an environment where its human companion has lots of time to play games with it such as fetch or tug-of-war.

Many owners will run alongside their dogs for some intense cardio exercise. If you travel often and for long periods, this may not be a good fit for you as it will require even more individual attention from you.

A Jack Russell Terrier thrives on having its owner around and thus prefers not to be left alone frequently.

If you work long hours or need to leave your dog home alone often, this may lead to anxiety in your terrier which over time can lead to compulsive behaviors such as excessive barking, digging, or chewing.

Care & Grooming

The Jack Russell Terrier has a relatively short coat that is generally easy to care for. With the exception of bathing and clipping its nails, there’s no need to bathe your dog very often.

A brush will suffice for removing dead hairs as it can be easily brushed when shedding season occurs. An everyday brush can be used three times a week or more prior to grooming your dog so as to prevent matting.

Regular brushing will help increase the life of your dog’s coat which should not be cut or shaved at any point for any reason. The only thing you should never do is wash your Jack Russell Terrier in water, which may lead to the matting of her hair if not groomed regularly.

This breed does not tolerate cold weather well and requires daily access to some degree of sunlight so it doesn’t overheat, resulting in possible heatstroke.

A Jack Russell Terrier that is properly cared for will require no special grooming. However, for the sake of their health, owners should regularly examine their ears and eyes for signs of infection or discharge.

A Jack Russell Terrier may develop skin infections that can be treated with antibiotics. In order to keep the skin around its eyes clean and healthy, it would be best to brush them frequently with a gentle dog toothbrush.

If needed you may use an eye ointment that is available from your veterinarian or simply apply a tiny bit of diluted human baby oil to the eyes twice a week in addition to regular brushing.


The Jack Russell Terrier is a carnivore, which means that it needs a diet supplemented with protein and nutrients. It needs to be fed three to four times per day with one large meal and small snacks every few hours.

If you are concerned about your dog’s weight, you should check its body condition every month or two because even though the Jack Russel Terrier can tolerate being overweight, it may show signs of health problems when it becomes overweight.

A good way to tell whether or not your dog is underweight is to gently feel it on the ribs, loin area, and hips. Be sure not to use the method when your dog is excited as this will cause discomfort and possibly over-stimulation for which you will benefit little.

Your veterinarian can tell you what its ideal weight should be given its age, breed of dog, and gender.


Jack Russel Terriers need to eat an appropriate amount of protein and nutrients in order to maintain proper health. On average, they require 20 calories per pound (50 calories per Kg) of weight for daily nutrition.

While this is a general guideline, your dog’s size, age, and activity level will determine the exact amount of food it needs to consume each day.

The best way to keep your Jack Russel Terrier slim is by feeding it smaller meals several times a day instead of one large meal that can lead to excessive energy consumption. Small snacks can be fed every few hours as necessary.

In addition, when you are going on walks or playing games of fetch with your dog, you should give it slightly moist treats as well in order to keep it hydrated throughout the activity period aside from its normal water intake.

Children And Other Pets

Jack Russel Terriers are highly intelligent dogs that are generally trustworthy with other animals, especially children. For this reason, it would be best to adopt an adult or two so as not to be placing a newborn in an environment where they may injure themselves.

While your Jack Russel Terrier should not be left alone or unattended around small children, it can be left alone with adults at an age when small children are no longer in the house.

If you have cats or other pets that you feel your Jack Russell Terrier may have issues with, it would also be wise for you to consider adopting a second Jack Russel Terrier to prevent any aggression from developing between them.

It is always advised that dogs not interact with other pets and remember that there is a big difference between playtime and real fighting. If your dog does start playing too roughly and aggressively with another dog, it is recommended that you separate the two dogs immediately before anything serious happens.


Jack Russell Terriers can be great indoor pets if you have asthma or allergies, but they can still trigger an allergic reaction. If you have asthma, you know that this can cause difficulty breathing, and if you have allergies that are seasonal, you know that this can cause sneezing and watery eyes, among other symptoms.

While a Jack Russell’s allergy symptoms may not be long-lasting and as severe as some other animals, they might just be enough to keep you from enjoying your time with them.


jack russell terrier training

The Jack Russell Terrier can be very obedient and loyal to its master if treated well. It is best that training starts at an early age, so it will get used to it and maintain its independence. Owners should begin training their Jack Russel Terriers by keeping them on a leash since it is a natural-born hunter.

However, training must also include daily games such as fetching a ball and tug-of-war. This not only strengthens the bond between the dog and its owner but also helps prevent boredom from setting in. The most important thing you can do for your Jack Russel Terrier is to socialize them from an early age.
