Jack russell terrier care

The JRT robe is not too demanding to care for.

During the molting period, smooth-haired dogs should be combed several times a week, and apart from that, you can limit this activity and do it once a week.

Coarse-haired dogs require trimming every 2-3 months.

Bath when needed.

White or hypoallergenic shampoos can be used as these dogs are prone to skin allergies.

Jack russell terrier disease

Jack russell terrier disease

Muscle tiredness

Also known as myasthenia gravis or simply myasthenia gravis is a neuromuscular disease and consists in a disturbance of the flow of nerve stimuli to skeletal muscles due to the inborn lack of receptors for Ach (acetylcholine) or as an acquired disease.

The inborn form that is present in this race is already showing up in puppies several weeks old as:

  • stiff gait,
  • shuffling limbs,
  • falling over.

The acquired form manifests itself at different ages, most often with muscle weakness during and immediately after exercise, and their regeneration after rest.

It may accompany the disease expansion of the esophagus or thymoma. The treatment uses acetylcholinesterase drugs to increase muscle endurance.

Lens dislocation

Lens dislocation consists in its displacement as a result of breaking the ligaments that support it.

It is quite a medical condition characteristic of terriers, autosomal dominant.

The changes often affect both eyes and can lead to cataracts and secondary glaucoma. The recommended treatment is the use of anti-inflammatory drugs and, most often, surgical removal of the displaced lens.

Malesiosis

Malesiosis this fungal dermatitis caused by the commensal Malassezia pachydermatis.

It accompanies diseases with the weakening of the skin barrier, such as e.g. allergies, hormonal disorders or bacterial infections, and can also occur with long-term use of glucocorticosteroids.

Skin changes occur in the form of:

  • alopecia,
  • skin hyperpigmentation,
  • redness and the appearance of a characteristic yeast-scented, light brown coating.

The skin is oily, and the most frequent rash and discharge are:

  • in ears,
  • between the fingers,
  • in the abdominal region of the neck,
  • in skin folds.

We treat malasiosia topically and generally with antifungal preparations. It is also important to identify and treat the underlying disease.

Fish scales

This disease is rare in dogs and may affect one or more animals in a litter.

It manifests itself in characteristic scales that stick firmly to the skin and come off it in patches.

The epidermis of the finger pads and the nasal mirror is also hyperkeratotic.

Ichthyosis is diagnosed by histopathological examination and there is no causal treatment.

Therapy uses unsaturated fatty acids and baths in anti-seborrheic shampoos. The prognosis is cautious.

Diabetes

Diabetes mellitus is a metabolic disease in which glucose metabolism is disturbed due to the deficiency or lack of insulin, its receptors or the inability to transmit a signal at the correct amount.

There are two types of diabetes:

  1. Type 1 - insulin-dependent (the beta cells of the pancreas are destroyed and, as a consequence, no insulin is produced, and thus the blood glucose increases).
  2. Type 2 - non-insulin dependent (most common in obese dogs; characterized by a relative insulin deficiency - receptor resistance or pancreatic beta cell dysfunction).

The most common clinical symptoms include:

  • polydipsia (increased thirst),
  • polyuria (increased urination),
  • increase in appetite,
  • losing weight.

Depending on the type of diabetes, a diet or exogenous insulin is used.

Diabetes mellitus can also accompany other diseases, such as:

  • Cushing's disease,
  • inflammation of the pancreas,
  • Hypothyroidism.

You will learn everything about this disease in the article "Diabetes in dogs " - I encourage you to read.

Aseptic necrosis of the femoral head

Otherwise known as Legg Perthes Calve disease.

The vascularization of the femoral head and sometimes the femoral neck is disturbed, which leads to its deformation and severe pain.

The disease manifests itself as lameness or lack of straining on the limb, most often in several-month-old puppies.

Diagnostics includes an X-ray image, and treatment includes surgical resection of the femoral head.

Patellar dislocation

A kneecap dislocation is the dislocation of the kneecap to the medial or lateral side due to a too shallow femoral block.

The severity of the dislocation is determined on a 4-point scale:

  • 1 - no or rarely occurring lameness and protrusion of the kneecap under pressure in the examination.
  • 2 - temporary lameness.
  • 3 - constant lameness - the kneecap can be adjusted, but falls out spontaneously; there is the so-called. "Sessile " limbs.
  • 4 - permanent lameness - the kneecap is outside the block and cannot be adjusted.

First-degree cases can be physiotherapy, but significant lameness requires surgery.

Pituitary tumor

Cancerous cells in the pituitary gland produce excessive amounts ACTH, which leads to bilateral adrenal hyperplasia and increased production of glucocorticoids, i.e Cushing's disease.

In the case of Jack Russell, it concerns a slightly greater percentage females (55-60%) and older dogs.

Excess cortisol causes metabolic disorders, leads to:

  • muscle wasting,
  • pressure disorders,
  • different distribution of adipose tissue,
  • skin thinning,
  • liver enlargement.

The most common symptoms are:

  • polydipsia,
  • polyuria,
  • enlargement of the outline of the abdomen,
  • increased yawning.

Diagnostics is based on urine and blood tests - general and specialized dexamethasone inhibition and ACTH stimulation tests. Treatment of pituitary-dependent Cushing's syndrome is practically only symptomatic.
