Can a dog lose hair because of this?

Yes, dogs can scratch their fur off, and this itching can be from the fleas and ticks... your poor parasite-ridden dog! Take good care of her! :)

Can a dog lose hair because of this?

Go get a second opinion. I'm not too sure giardia would cause hair loss. Just get another opinion and take previous bills with you to show them what you've done.

Can a dog lose hair because of this?

Dogs can lose hair for a number of different reasons. Some of the more common are:

1) Mange. This is a skin condition caused by mites, and there are a couple of different kinds. It can result in hair loss in dogs because the dog will often bite at the itching areas repeatedly, wearing away the hair. Also, some of the mites actually infest the base of the hairs and eat the hair follicle, causing them to fall out.

2) Skin infections. Sometimes bacteria or a fungus can infect the dog's skin, and this can result in the dog having its fur come out near the infection.

3) Fleas. Fleas can cause hair loss in two ways: first, because of the constant scratching and biting of the hair. Second, there is an allergic condition caused by fleas called dermatitis. This results in a general skin condition that can cause hair loss as well.

4) Allergies. Sometimes allergies result in skin problems that include hair loss. A dog can be allergic to a wide range of different things, including basically anything a person could be allergic to.

5) Obsessive Compulsive Disorder in Dogs. Some breeds are predisposed to get this, others aren't. Yes, dogs and other pets can get OCD, and several other psychological problems like depression. Any of these can cause hair loss because many dogs will bite at themselves or repeatedly chew at their fur. For example, Dobermans are genetically prone to get it and usually suck on their own skin over and over. OCD in dogs is mainly a response to stress.

6) Pregnancy. Sounds weird, but it's true - some female dogs lose hair around their coat when they're pregnant.

7) Ringworm in dogs. This is basically a fungus, and it will cause the dog to lose fur around where the infection is.

What causes hair to fall out?

Skin parasites and infections, allergies, nutrition, organ function, blood flow, hormones, topical medications, and behavior all influence hair growth and hair loss.

Skin parasites and infections

Parasitic fleas, lice, and mites cause hair loss because they cause itching. The pet scratches or bites vigorously and the hair is chewed or broken off. The moist, chewed skin is ripe for skin infections with yeast, ringworm, or bacteria. The yeast, ringworm, and bacteria also cause itching, and even more hair is chewed off.

Where the hair loss occurs suggests which parasite is involved. Fleas attack the back over hips; lice often attack the back and back legs; mites focus on eyes, ears, mouth, and elbows.

Allergies

When humans are allergic, our eyes water, our noses run, and we itch. With pets, allergies are expressed in the skin and ears rather than the eyes and nose. So, allergic pets have itchy skin, and in response they scratch or chew out their hair. Pets can be allergic to

foods,

inhaled allergens, and

materials their skin contacts.

Common food allergies are caused by grains (wheat, corn, soy), meats and fish (beef, lamb, pork, salmon), milk and yeast. Common inhaled allergens are pollens, cigarette smoke, and perfumes閳ユ攨specially those added to cat litter. Pets can experience contact allergies when they walk through grass, across chemically treated decks, on carpets with chemical in the carpet or underpad.

Oral, topical, and injected medications

Several oral, topical and injected medications cause hair loss. For example, high doses or long-term use of oral, topical, or injected steroids can cause hair follicles to shrink and hair to fall out. Hair regrowth is delayed until follicles are no longer influenced by high steroid levels. Some topically applied flea medications cause hair loss at the area of application. Injected vaccines cause hair loss at the injection site and in some pets there is further widespread hair loss over the next few months. Fortunately, this is rare. With all these medications, hair is lost from the follicle rather than bitten off.

Behavior

Pets can develop hair loss because they have behavioral problems. For example, dogs with a separation anxiety behavior disorder lick patches of hair off their legs. This is called acral lick dermatitis. With acral lick dermatitis, dogs can lick so unrelentingly that their skin breaks down and becomes infected. What began as anxiety turns into a bacterial and yeast infection that is difficult to cure because the pet licks it whenever left alone. The areas normally involved are the front legs just above the wrist (carpus) and back legs near the ankle (tarsus).

Nutrition

Hair requires a constant supply of nutrients to remain anchored in the skin. Nutrients that support healthy hair are the same as those that support healthy skin: vitamins, minerals, antioxidants, and Omega 3 and Omega 6 fatty acids. Hair that doesn閳ユ獩 receive a balanced supply of nutrients becomes dull, loosens, and falls out. For example, pets on starvation diets have thin, dull coats. Hair loss due to poor nutrition often involves the whole pet, but may be most obvious over areas that are easily worn and over the back and hips where hair follicles have shorter growth cycles and longer inactive periods.

There are many diseases and conditions which can cause a dog to lose hair. Some of these may be considered normal, others can indicate a serious disease is present. Most of the conditions which result in hair loss are included in the table below, though some of them may be rare. This extensive list helps you understand why a quick diagnosis may be difficult to make, and various diagnostic tests may need to be performed. The most common conditions causing hair loss are color-coded gray in the table (some may be more common in certain geographical areas).

Condition Description Symptoms Diagnosis Treatment

Acanthosis nigricans Inherited form seen in Dachshunds; secondary form caused by friction, hormonal abnormalities, or hypersensitivities Darkening of the skin; in secondary form see scratching and hair loss History, physical exam; in secondary form, testing to determine underlying cause Primary: no treatment; secondary: treat underlying disease; in some cases, steroids and Vitamin E supplementation

Acral lick dermatitis (neurodermatitis)

Self-licking in dogs results in self-trauma; possible causes include anxiety, boredom, stress (e.g., new member in household); licking can develop into an obsessive behavior

Red, hairless, well-circumscribed, sometimes raised lesion usually on the leg; if chronic, will drain

Exclude other causes; history important

Relieve underlying cause e.g., anxiety; restrict licking, e.g., elizabethan collar; behavior modifying medication may be necessary

Adrenal sex hormone responsive dermatosis More common in Pomeranians, Chows, Keeshonden, and Samoyeds Hair loss starts on neck, tail, back of thighs, and progresses to trunk; dog appears to have a 'puppy coat'; skin darkens Biopsy; eliminate other causes Mitotane is optional

Allergic and irritant contact dermatitis

Generally requires multiple exposures.

Red skin and small bumps or blisters on the areas of skin that are sparsely haired and directly exposed to the offending substance, itching; hair loss in chronic conditions

Patch test, exclusion trials

Restrict exposure to the allergen or contact irritant in the dog's environment; steroids, antihistamines

Can a dog lose hair because of this?

Yes, if your dog is illergic to flea bites she will scratch so much she'll lose her hair. I had a cat lose all her hair around her face and ears each year due to flea bites. Make sure she is put on a good flea prevention medication and give her a flea bath during flea season to help with the scratching. They do sell a product in the pet stores called sulfadine, it's good to put a little on their bare patches it helps with itching.

If it's mange they will do a skin scraping and look under the microscope to see if they can see sarcophic manage mites, it's treatable but you might want to keep her away from other dogs if that's what she has.

They should do a skin scraping regardless to rule out anything other than flea bites.

Good luck

Can a dog lose hair because of this?

Fleas can kill your pet if not treated. I like frontline. If it is mange he should have treated it. My dog was losing her hair when I rescued her. A good dog food can make a difference. I like Royal Canin. Her hair did come back. I think I would research into finding a new vet. My girl is also a chihuahua.
