Hair Loss in Dogs and Bald Patches

The bald spots on dogs are more common than you think and are the source of different causes that today we will list in order to give the best treatment for their disappearance.

Our furry ones have a layer of hair that protects their skin that, normally, is shed naturally twice a year, but other times it is not.

When the hair falls out, and it is not due to something natural, it could be due to some type of disease.

If the hair follicles of the dog’s hair are damaged, the hair does not grow normally as it should, that is, it would be dull and dull hair.

When the disease that causes baldness in the dog completely destroys the hair follicle, that is when the hair is completely lost.

The result of all this is to observe that the dog has areas on its body without hair.

These areas can be large or small, with different shapes and in different places.

THE COAT OF DOGS IS DIFFERENT

All dogs have different types of coats depending on their breed.

Some are thick, smooth, soft, long, short, among others, however, although they are different coats, to be healthy, they should always have shine, look strong, and healthy.

In addition, the fur must be distributed in the same way throughout the body, that is, without having hairless areas.

 WHY DO DOGS LOSE HAIR? 

When winter arrives, that is, the time of year when it is colder, many dogs tend to shed their fur, however, many times the loss of hair in dogs is not for that reason.

Therefore, it may be that the dog has something else, such as a skin condition, alterations in its metabolism, some diseases, among others.

Many experts indicate that if the baldness in a dog is due to some congenital factor, this means that baldness may be more prone in some breeds, it can even influence their hair color.

On the other hand, if the dog loses hair little by little, the causes may not be something congenital, but due to other factors.

Some causes of bald spots in dogs are:

ALLERGIES

Many of the allergies that dogs can have that cause bald spots in dogs are due to the environment where the dog surrounds itself.

Some causes can be mites, pollen, mold, among others.

Others may also be due to allergies to some foods, that is, food allergies that are very common.

Itching is the most common symptom of an allergy, in simple words, it is an annoying itch that can be felt in the body and that causes the urge or immediate need to scratch.

When a dog scratches itself in that way, it causes the hair to fall out and that is the beginning of the bald spot.

To improve allergies, it is important to have the dog evaluated by a veterinarian to determine its cause.

Once it is determined, it will be necessary to comply with the treatment step by step, until the end.

Your vet may run some allergy tests and exams on your dog to find the allergen.

The important thing is that once detected, the dog does not have contact with the allergen.

ATOPIC DERMATITIS

Atopic dermatitis is very common in some dogs and manifests with itching or erythema.

When dogs are young, less than a year old, and have this disease, it is not common to see signs of it in the dog.

But from the first year, it is where the symptoms are much more evident, exactly, between the first year and the third year of life.

Then, as the days go by, the disease progresses and gets worse.

Symptoms of this disease can be observed in some parts of the dog’s body.

Those parts are:

  • Ears.
  • Feet and legs.
  • Face.
  • Armpits
  • Ears.
  • English.
  • Perineum.

There are cases where the symptoms of bald spots in dogs are seen throughout the dog’s body.

The most common symptoms are:

  • Inflammation.
  • Red spots.
  • Papules
  • Hairless areas.
  • Bacterial infections in some parts.
  • Presence of scabs.
  • Others.

Internal and external parasites:

Hygiene is something fundamental that every adopter must try to fulfill well with his pet.

If the dog does not have proper hygiene, it can present some diseases.

It is also important that the dog is dewormed to prevent the presence of internal and external parasites (ticks, fleas, others).

On the other hand, there is mange or ringworm, which causes the dog to lose hair around its ears, torso, abdomen, and eyes.

GENETICS AND BALDNESS

One of the most common causes of baldness or lack of hair in dogs is genetics.

This is because some breeds are more prone to baldness than others.

Some more prone dog breeds are the Chinese Crested or other more popular or known breeds such as the Chihuahua, the Doberman Pinscher, among others.

The latter have baldness in different parts of the body.

Bald spots in dogs in these breeds are seen on parts of the body such as: the back, ears, torso, others.

ULCERS OR CORNS

When the dog has ulcers or calluses, the hair in the area disappears.

This injury is located in the elbows and other places on your body, as well as your hips.

As the days go by, the fur of those points or specific places, when it comes into contact with hard surfaces, gradually disappears.

While that friction occurs that causes the hair to fall, it is where the callus forms, once the skin hardens.

CUSHING’S DISEASE

It is one of the most common endocrine diseases in some dogs, especially in middle and elderly dogs.

This endocrine disease is associated with an excess of cortisol, which is produced by the small glands that are in the abdomen, that is, the adrenal glands.

This disease has different symptoms and one of them is baldness in dogs. Other symptoms are darkened skin, prominent belly, among others.

It is important to mention that this disease affects more dogs that have used corticosteroids in excess.

FOOD ALLERGIES, A MAJOR CAUSE OF BALD SPOTS IN DOGS

It is important that adopters take into account the type of food they give their dogs.

That depends a lot on whether their coat remains healthy and strong.

A diet lacking in nutrients will not only make the hair lack strength or shine but also make the dog more prone to diseases.

Dogs need a balanced diet with all the necessary nutrients for their growth.

The vet can indicate what type of diet each dog needs and how much.

However, it is important to include omega 3 and 6 in your food, which is found in vegetable oils. The dog must have a diet rich in fatty acids.

The vegetable oils help the skin keep your dog’s impermeable barrier function.

This helps more cells to renew themselves. Simply put, it would mean healthy skin.

On the other hand, it is also important to include whole grains, which are rich in vitamin H (biotin).

This vitamin H, if the dog has an injury due to the loss of its hair, the cells that are damaged would regenerate.

MITES AND BALD SPOTS IN DOGS 

Dogs can easily be exposed to mites, parasites that can cause baldness.

Mites cause two types of scabies:

  • Demodectic mange: 

To recognize demodectic mange, one must be aware of parts of the dog’s body that are balding.

It is important to mention that demodectic mange is more common in puppy dogs. This scabies is caused by Demodex canis mites.

  • Sarcoptic mange:

This mange produces a very strong itch in the dog. In that sense, the dog will scratch constantly, it will not be able to stop doing it and that will cause it to hurt itself.

This type of scabies is contagious, even to humans. By diagnosing it in time, it can be treated and prevent it from spreading. This scabies is caused by the Sarcoptes scabies mites.

THE VET AND BALDNESS 

There are different reasons why bald spots appear in dogs.

The adopter should avoid self-medicating the dog and let the professional be the one to evaluate it and issue the correct diagnosis for its cure.

Bald spots are often due to simple reasons or something more complex and, therefore, the first thing to do is take the dog to see the vet.

When baldness is due to an organic cause, the most common is that the dog is treated with antibiotics or dewormers; as long as the veterinarian prescribes it.

On the other hand, baldness can be the product of stress or anxiety.

In that sense, it will be necessary to make changes in the routine and habits in general of the dog.

Some options are to exercise more, mental stimulation, among others.

Before going to the vet, it is important that the adopter observe the dog to describe well in the medical consultation, the symptoms that the dog has presented.

When going to the consultation with the veterinarian it is necessary to know the answers to some of the following questions.

  • Does the dog have an itch? Since when?
  • Do you scratch very often?
  • What type of food do you give the dog? Do I think or homemade food?
  • Do you have only one affected dog or are there more at home?
  • Does the dog take any kind of medication? Which?
  • Do you have any strange symptoms?

It is necessary for the adopter to be as clear and specific as possible, so that the doctor can have all the necessary information and, together with the physical diagnosis or some tests, determine what causes baldness in order to treat it appropriately with the ideal treatment.

No matter how old the dog is or what its breed is, all of them could be bald.

However, when baldness is caused by a disease, it could interfere with the race.

It is important to remember that if a dog is balding, it clearly indicates a potential health problem that the adopter must quickly address.

HOW TO IMPROVE THE HEALTH OF THE HAIR OF DOGS?

The adopter must ensure daily hygiene habits for his dog in order to keep him clean and healthy.

It is important for the adopter to maintain a brushing and bathing routine :

Brushing should be every day. Many dogs lose hair and it is important to remove it from their body.

When it comes to bathing, dogs should be bathed once a month, unless they get dirty a lot.

But a monthly bath with the right products for your skin will be important for your health and general care.

On the other hand, it is advisable to use some nutritional supplements in the bathroom, both in brushing and in the bathroom, which helps the dog not to shed a lot of hair, this in the case of healthy dogs.

As for the dog that already has baldness, they can also be used to complement the treatment they have, as long as it is known what causes the baldness and that the doctor approves the use of these drugs.

I THINK OR HOMEMADE FOOD FOR A HEALTHY COAT

Food is important for the dog to be healthy, that includes its coat.

Therefore, it is important to include in your diet some supplements that will help your hair grow strong and healthy.

This also includes strengthening the dog’s nails.

The food should include zinc, fatty acids, among others.

It is always important that the vet evaluates the dog to know the amount and what types of supplements are good for his coat.

These are usually found in the feed. To choose the correct one it is necessary to read its ingredients, but always with the approval of the veterinarian.

Many adopters prefer to give their dogs a homemade diet, so it would be important not to stop including foods rich in fatty acids (Omega 3 and 6).

These foods are tuna, salmon, oatmeal, olive oil, chia seed, among others.

This type of homemade food is more difficult to prepare, it takes time, but in the end, it depends on each adopter.

The important thing is that the adopter makes sure to include the correct ingredients.

Note: It does not matter if the adopter chooses to feed his dog dry or homemade dog food, as long as each serving covers the nutrients and vitamins that the dog’s body needs.

All this would help considerably to strengthen its coat and prevent baldness.

What is grounding

An earthing (combination of protective conductors and earth electrode) is a permanent, well-conducting connection to the earth, without the interposition of a fuse or switch. An earthing consists of one or more earth electrodes, an earth conductor, and protective conductors.

how ground electrode

How to make a ground electrode. The spreading resistance of the ground electrode must be less than 100 ohms. In order not to create any additional conditions for the installation, it is best to ensure that the spreading resistance of the earth electrode is less than 30 ohms. The ground electrode is placed as a ground loop. If this is not possible, use is made of “additional earth electrodes”, such as the metal conductor buried horizontally in the ground, the bars, pins, or conductors driven vertically or obliquely into the ground.

The ground loop

For any new building where the bottom of the foundation trench is at least 60 cm deep, the earth electrode must include at least one loop placed on the bottom of the foundation trench below the outer walls. The ground loop must consist of a solid conductor with a circular cross-section of at least 35 mm2 and without welding. As far as possible, the loop comprises only one conductor, however, the use of several interconnected conductors is allowed in some cases. The ground loop conductor must be bare hardened electrolytic copper or leaded copper. The latter should be used if the site in which the conductor is placed is not likely to provide the necessary guarantees against harmful corrosive action on the copper. The earth loop must be installed directly against the ground and covered with earth in such a way that it does not come into contact with the material of the foundation walls (mortar, concrete, reinforcement … ). The ends of the ground loop must remain accessible for examination. If the ground loop is composed of several conductors placed in series, the ends of each conductor and their connections must remain accessible for examination.

additional ground electrode

If a ground loop cannot be installed (e.g. when the depth of the foundation trench is insufficient) or when the spreading resistance of the ground electrode formed by the ground loop is insufficiently small, ground electrodes called “additional ground electrodes” must be used.

The metal conductor buried horizontally in the ground

The metal conductor buried horizontally in the ground must be a solid conductor of circular cross-section made of copper or leaded copper (same condition as the ground loop). Its cross-section is at least 35 mm2 and the conductor must be buried at least 0.80 m deep.

Metal bars, pins, or conductors are driven vertically or obliquely into the ground

The grounding bars or pins must be at least 1.50 m long. The driven length below the level -0.60 m must be at least 1.50 m.

Grounding bars

Grounding bars must be full and of circular cross-section. Their diameter must be at least 14 mm if they are made of copper or copper-plated steel or 19 mm if they are made of galvanized steel.

Ground pins

The grounding pins consist of a straight or helical metal profile. If the grounding pin is made of galvanized steel, the side of the profile must be at least 60 mm with a thickness of the wings and the core of at least 4 mm. the minimum cross-section must have a diameter of at least 19 mm. The thickness of the wings must be at least 3 mm.

Ground Driven Conductors

The conductors driven into the ground consist of bare hardened electrolytic copper with a cross-section of at least 50 mm2. The conductor must be driven into the ground by mechanical vibrations. A steelhead must be placed on the end of the guide in order to avoid any damage during driving.

What is a capacitor

A capacitor (available from a few cents to tens of euros) is an electrical component that builds up, stores and discharges charge. The charge build-up occurs between plates or conductors that are separated from each other; This is also reflected in the symbol for a capacitor:

  • ||-

The amount of charge (Q), or the capacitance (C), of a capacitor, is expressed in farads (F).

Formula

A capacitor that has a charge of 1 coulomb, where the voltage between the plates is 1 volt, has a capacitance of 1 farad.

The relationship in formula form is:

Q = C x U

Where the charge Q in coulombs on the capacitor is the result of the multiplication between the voltage U in volts across the capacitor and the capacitance C in farads.

Types of capacitors and their application

There are different types of capacitors intended for different applications. In addition, capacitors are made of different materials. There are different types of capacitors, some of them are:

  • ceramic capacitors; small capacitance and high voltage, also called circa (ceramic capacitor)
  • mica; small capacity and high voltage
  • electrolytic capacitor; high capacitance, low ohmic resistance, often used as voltage stabilization, also called el cap (electrolytic capacitor)
  • variable; are used when fine-tuning is required, often in transmission technology, also called trimmers (such as variable resistors)

The capacitor in an electrical circuit

Like other electronic components, the capacitor also has certain properties in an electronic circuit. Without going into too much detail about the infinitely many applications of the capacitor, whether or not in combination with other types of components, only the basic circuits will be discussed here.

Parallel connection

If capacitors are included in parallel in a circuit, the sum of the individual capacitances may be regarded as replacement capacitance. In a parallel arrangement, the voltage across the capacitors is equal, however, the charge will be distributed across them.

C replacement = C1 + C2 + Cn

Series connection

In a series circuit of capacitors, the current flowing in the individual capacitors is the same. The voltage across the entire series circuit is the sum of the individual voltages across the capacitor.

Itotal = I1 = I2 = In

Utotal=U1+U2+Un

The replacement capacitance of capacitors in a series circuit, as is the case for resistors in series, is the inverse of the sum of the inverses of the individual capacitances.

1/Creplacement = (1/C1 + 1/C2 + 1/Cn)

Capacity indication

There are capacitors where the capacitance including the unit can be found on the housing, eg 100 F. If there is no unit after the value, then pF (picofarad) can generally be assumed.

There are also capacitors that use color coding for electronic components. The first band indicates the tens, the second band the units, and the third band the factor by which the multiplication takes place. The results of the 3 bands mentioned are in the unit pF. The fourth band represents the tolerance and the fifth band the maximum allowable tension.

In addition, there are capacitors where the capacitance is determined by an imprint of 3 digits; for example, an imprint of 103 has an actual capacitance of 10 x 103 = 10,000 pF = 10 nF

Finally, the capacity can also be measured using so-called capacity meters.
