The frequency that you`ll need to bathe your Malinois depends on how active a lifestyle they lead. They can be washed as frequently as once a week up to no longer than every six weeks. Regular baths, blowouts, and frequent brushing lay the groundwork for maintaining a healthy coat and skin.
Anxiety can trigger a number of health problems in humans, including hair loss. This is also true for canines. When your dog is nervous on a car ride or is fearful at the veterinarian`s office, you may have noticed that they shed a lot.

“Vitamins are essential for healthy hair growth and may help in preventing hair shedding and thinning,” says Michele Green, M.D., a cosmetic dermatologist in New York. “The best vitamins for hair growth include B vitamins, vitamin D, vitamin E, zinc, biotin and iron.
In healthy individuals biotin does not need to be supplemented [14]. Only riboflavin, biotin, folate, and vitamin B12 deficiencies have been associated with hair loss.
In the absence of deficiency, supplementation may actually prove harmful to hair. Over-supplementation of certain nutrients, including selenium, Vitamin A, and Vitamin E, has actually been linked to hair loss [4,8–11].
B12 Deficiency Symptoms

Symptoms of low B12 often occur when blood levels drop below 300 ng/l and include hair loss, breathlessness, lack of energy palpitations, bleeding gums, mouth ulcers, tingling in the hands and feet.

Treats should not exceed more than 10 percent of your pet’s daily calories. There are healthier treats that can be offered to your pet to keep calories lower yet provide a fuller sensation.

Q. Russian blue mix cat – usually velvet soft coat but hair on back hind qtrs. is thinning, remaining hair seems less velvety than normal
ANSWER : A. Changes in coat appearance can be caused by a number of things. In older cats, hair loss or changes in coat and skin confirmation may indicate a metabolic issue such as thyroid problems. Cats can begin to lose hair and may also show other changes such as weight changes or appetite changes. Blood work is usually done to check for this, and most pets do very well with a daily medication treatment.

Hair loss can also be caused by mites on the skin, external parasites or even skin and fungal infections. These may cause red bumps or sores to appear on the skin in addition to the hair loss and coat changes. Your vet can take a skin scraping of the area to check for mites and infections, and a preventive flea treatment can remove any external parasites. If an infection or mites are present, your vet can also prescribe an antibiotic or topical cream to treat.

After any treatment it may take a month or two for completely bald patches to grow back in. This is normal as the skin and follicles need some time to heal prior to beginning the hair growth cycle again.

Q. My pet shows weight loss and has a hard time walking, like he has lost strength in his legs and has no control to maintain balance. What’s wrong?
ANSWER : A. Loss of balance or inability to control the limbs can be caused by a wide range of problems and is usually cause for concern. Damage to the nerves or muscles can cause loss of balance, as well as neurological disease or some illnesses. Having your vet perform a complete examination is needed to determine the exact cause.

Weight loss can refer to the actual loss of fat and weight on your dog, or may also be due to the loss of muscle tone in the body. If there is a problem with one of the limbs, it may be that the weight loss you are seeing is actually loss of muscle in that area. Weight loss can again be caused by a wide range of problems from neurologic disease, illness, parasites or disease. Making an appointment with your vet is best.

Q. Dachshund has symetrical hair loss since aged 6 mth now 1 treated for mange had testicle removed from abdo still no better what’s next best step ?
ANSWER : A. Has hormonal disease like hypothyroidism been ruled out? That is a hormonal disease that is common causes of symmetrical hair loss, and it can be genetic, so you would see it in a dog that’s very young like yours. I agree that treating for mange was also a good idea, since that can cause hair loss as well and sometimes we can’ actually find the mites on a skin scraping.

Was a biopsy performed on the testicle? Because intra-abdominal testicles frequently turn into Sertoli cell tumors, which also cause symmetrical hair loss. If a biopsy was performed you should know for sure whether that was the cause of the hair loss or not. If the testicle wasn’t cancerous and removing it did not resolve the hair loss then the next step is a skin biopsy, unfortunately. Sounds frustrating – good luck.

Q. My cat is lossing a lot of hair she is 13 yrs old and been to the vet twice and had antibiotic and the next time steroid and advantage plus . I’m at
ANSWER : A. There are many possible causes of hair losss as I’m sure your veterinarian has explained to you. At 13 years old, your cat is in the right age-range for diseases of the thyroid gland to develop. Itchiness and hair loss can sometimes be a symptom of thyroid disorders. It may be necessary to have a full senior blood work up to check the thyroid levels and overall health of your senior cat. Other causes of hair loss include allergies to fleas and contact dermatitis (allergic to some chemical in the enviroment such as scented cat litter, air freshners, laundry products, floor cleaners, etc). Hair loss is a symptom of a larger problem and can be frustrating to treat. Try to get to the underlying cause.

Q. My cat just developed extreme irritability on his butt and sides. He’s a 6 year old Maine Coon. It seems like he is in pain. No parasites or fleas.
ANSWER : A. It is possible that a sore or skin problem has started on him that is causing your cat some stress. If the irritation is situated around his back end and anus, constipation or diarrhea can sometimes cause irritation. The anal glands are also located in that area and can become full and irritated.

if he is experiencing changes to the skin or hair on his back and sides, it is possible that an underlying infection such as skin or fungus, or even a metabolic condition are causing the change. Preventing him from licking or chewing at the area can help prevent secondary infections from forming. If the irritation continues or worsens, then scheduling a vet visit can help determine the cause.

Q. My 12 year old cat is constantly grooming and scratching to the extent that she is pulling her hair out in spots. She is also losing weight.
ANSWER : A. Weight loss in older cats, especially when coupled with continued or increased appetite can indicate diabetes or hyperthyroidism. I recommend getting your cat in to see your vet as soon as possible for an exam and comprehensive labwork.

Skin problems can have a variety of causes, sometimes more than one. It is important to have the problem checked by your vet to determine if there is a medical cause for your pet’s skin issues and treat accordingly.

In pets of all ages, fleas, food allergies and exposure to chemical irritants such as cleaners and soaps can be a cause. Any one of these may not be enough to trigger the breakouts, depending on how sensitive your pet is, but a combination can be enough to start the itch-scratch cycle. Finding out the cause and eliminating it is the best course of action. With flea allergies, if your pet is sensitive enough, a single bite can cause them to break out scratch enough to tear their skin.

Check for fleas with a flea comb. Look for fleas and/or tiny black granules, like coarse black pepper. This is flea feces, consisting of digested, dried blood. You may find tiny white particles, like salt, which are the flea eggs. Applying a good topical monthly flea treatment and aggressively treating your house and yard will help break the flea life cycle.

If you use plastic bowls, this is a possible cause for hair loss, though this tends to be on the chin, where their skin touches the bowl while they eat. If you suspect this to be the culprit, try changing the bowls to glass, metal or ceramic.

Food allergies are often caused by sensitivity to a protein in the food. Hill’s Science Diet offers some non-prescription options for sensitive skin as well as prescription hypoallergenic foods for more severe cases. Royal Canin carries limited protein diets that may also offer some relief. Your vet can recommend a specific diet that will help.

If there is no relief or not enough, consider getting your pet checked by a veterinary dermatologist and having allergy testing done.
