Education and training Jack Russell Terrier

One of the most important jobs in the education of the Jack Russell terrier is its socialization.

Their primary instincts, their desire to hunt or chase other animals, are much stronger in this dog than in other terriers, so it is not easy to get them to establish a cordial relationship with pets of other species .

Nor is it easy to prevent you from repressing your desire to explore unfamiliar places. You have to be very careful when letting it run free, something totally discouraged unless you are in confined and safe areas or in the case of individuals with a high degree of obedience.

The best way to keep a calm and balanced Jack Russell terrier is, therefore, to provide them with all the activity and exercise he needs, which makes them not the best companion for a sedentary family or for living in an apartment in the city. town.

When it comes to your training and education, it is very important to use positive reinforcement . That is, rewarding the animal when it does something well or obeys an order, instead of yelling at it, being rude with it, or punishing it when it does something wrong.

Jack Russell Terrier breed diet

Apart from exercise, the owners of this breed must administer a series of very basic care to their dog to ensure that it lives healthy and happy. One of them is to watch your diet.

The diet of a Jack Russell terrier must be rich in proteins, basically of animal origin, to satisfy its energy demands and provide adequate nutrition to its muscles and its flexible skeletal system.

But at the same time, your food must also have a rich and balanced composition of quality fats (omega 3 and omega 6) to ensure the health of your eyes, skin and hair.

In recent years, the largest manufacturers of dog food have developed feed or kibbles specially designed for this type of dog. You can find it in specialized pet stores or conveniently on the Internet.

Jack Russell Terrier health and diseases

The Jack Russell terrier is a working dog and so far it has not suffered the consequences of fashion, it remains a strong, healthy breed and little exposed to serious diseases.

There are a few isolated cases of knee dislocation and the occasional skin and eye problem, but other than that, nothing of particular importance.

Regarding how long a Jack Russell lives, you should know that in this dog the longevity or hope is between 13 and 16 years with the correct health care and attention.

Thus, it is enough to periodically go to the veterinarian to complete the rigorous vaccinations, the internal and external deworming programs, and the control of the eyes, mouth and ears .

The veterinarian must also be in charge of monitoring its growth and weight, to keep this fantastic dog in optimal health .

In general, working breeds, those that have been selected for generations only on functional criteria, are usually healthy and robust .

The reason is clear: those who are looking for an active, courageous, determined and resistant dog with which to hunt use to breed only breeding pairs that perfectly meet these requirements, and only select from the litters the puppies closest to the dog. ideal they are looking for.

By tradition, puppies that are not chosen by the breeder themselves or destined for someone looking for a dog of these characteristics are eliminated, so the weakest and least prepared dogs are left out of the reproductive chain.

However, this only occurs with working breeds. With the evolution of cinofilia towards sentimental criteria in which other factors prevail, especially aesthetic ones, functionality and temperament are beginning to be left in the background and, almost without knowing it, diseases are introduced into the blood lines that weaken the capabilities of a race.

Specific care of the Jack Russell Terrier breed

As for how often you should bathe the Jack Russell , it will only be necessary when the dog is really dirty, since with regular brushing, the bath can be done every 4 or 6 months.

With this minimum care, it is possible to have a healthy, balanced and happy animal that makes the life of the whole family much more fun, since it does not stop encouraging them to play with it and to take it out for a walk or run outdoors.
