How to Identify Common Pet Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced pet care professionals :

Skin conditions in dogs and cats can be caused by nutritional deficiency or due to adverse reactions to food. The most common deficiencies are to zinc, vitamin A and polyunsaturated acids. Adverse reactions may be due to toxins within the diet or due to immunological or allergic reactions to the food.
If your dog is constantly itchy and scratching to the point of hair loss and redness, this is considered pruritus. It can be in one certain area or the whole body. Itching may be caused by several disorders, such as contact dermatitis, allergy, and infection.
However, if your dog is suffering from dry or itchy skin, they may benefit from a Vitamin E boost. If skin problems are localized, Vitamin E can be applied topically.
Some dogs get enough vitamin E from their diet, while others may need to add a supplement. If your dog is deficient in vitamin E, some of the signs include dry skin, dandruff and skin abrasions. Vitamin E can be orally supplemented, but vitamin E oil can also be applied directly to the skin.
Can too much vitamin B12 cause a rash or itchy skin? Yes, taking large amounts of vitamin 12 can cause a skin reaction in people who are sensitive to cobalt. The symptoms include an itchy rash. How do you know if you are allergic to B12 or cobalt?
Vitamin Deficiencies That Cause Hair Loss

Biotin: Dogs with this vitamin H deficiency have a dull coat, flaky skin, and hair loss. In one study, 60% of the dogs given a high dose of biotin (5 mg/10 kg/day) improved when given this vitamin even though they did not all have biotin deficiency.

Oatmeal is an age-old remedy for our dry, itchy skin that happens to be safe for use on our canine friends too! In fact, most doggy hypoallergenic shampoos include oatmeal as an active ingredient to soothe and fight irritation. Start by grinding plain oatmeal into a powder to sprinkle in your dog`s warm bath.
It`s Great For Their Skin & Coat

Olive oil contains phytonutrients, vitamin E, and omega-3 fatty acids that help keep your dog`s skin moisturized and well-nourished. These nutrients also benefit your dog`s coat, adding shine and strength to their hair.

Add an omega 3 supplement

Feed your pet a multivitamin with Omega 3 fatty acids, which may help restore your pet`s skin health and reduce hair loss. We`ll contact your Vet to verify.

Eggs are basically a blessing for dogs with unhealthy skin or coat because they contain lutein. Lutein is a type of carotenoid that keeps your pet`s skin hydrated as well as encourages tissue repair. Eggs are also a great source of zinc, a mineral that keeps skin healthy and coat shiny.
Green leafy vegetables are good source of vitamin K. Vitamin K is also found in liver, meat, milk, and egg yolk. The major clinical sign of vitamin K deficiency noticed in all species is the impairment of blood coagulation. Clinical signs include, but are not limited to, increased clotting time and hemorrhage.
All it takes is a tablespoon of olive oil numerous times a week, and the flaky skin will go away, leaving your dog with its shiny natural coat. The vitamin E and fatty acids in olive oil can help moisturize your dog`s coat. Half a tablespoon twice a day can help your over 90 pounds help you get rid of dry skin.
The Best Vitamins for Dry Skin

There are a variety of vitamins that can help to improve dry skin, including vitamin A, vitamin C, and vitamin E. These nutrients are thought to help increase the moisture content in your skin, as well as repair damaged skin cells and promote new cell growth.

There are quite a few differences between vitamin D and vitamin D3, but the main difference between them is that vitamin D is a fat-soluble vitamin that regulates calcium and phosphorous levels in the body, whereas the vitamin D3 is the natural form of vitamin D produced by the body from sunlight.
Orange. There are limited Vitamin D fruits. Around 75% of people worldwide are either allergic to dairy products or lactose intolerant; some are vegan. So, orange or orange juice is the best option with vitamin D and other nutrients such as calcium.
Deficiencies in other vitamins such as vitamins A, E and C can also contribute to hair loss, says Dr Abraham. Here`s what role these vitamins play in hair health: Vitamin A helps in the production of sebum, which is an oily substance that moisturises the scalp and prevents hair from becoming dry and brittle.
Studies show that too much vitamin A can contribute to hair loss, as can too much selenium, although more studies are needed to establish the latter relationship. Alopecia areata (AA) occurs when the immune system attacks the hair follicle. Studies have shown a relationship between AA and low vitamin D levels.
Vitamin A is an essential fat-soluble vitamin that has functions supporting vision, bone growth, reproduction, cellular differentiation and immune response in dogs( 1 ).
Ringworm fungus, pests like mange mites, and bacteria can all lead to infections that may ultimately cause bald spots on your dog. Along with hair loss around the ears, eyes, mouth, and elsewhere, signs your dog may have mites include oily skin, thickened skin, itching, and inflammation.
There are a few potential causes for why dogs bite themselves, including skin irritation or allergies, boredom or anxiety, and compulsive disorders. Some breeds of dogs in particular, such as English Bulldogs, French Bulldogs, and Pugs, seem to be more prone to this behavior than others.
When dogs develop allergies, it generally causes itchy and inflamed skin, respiratory disorders, and chronic skin and ear infections. Essential oils such as lavender, chamomile, and peppermint may be used to ease some of these symptoms. Other essential oils, like tea tree oil, can be quite toxic to your dog.
To best support your dog and healthy hair growth, feed a diet that`s rich in animal protein. The amino acids and fatty acids present in animal protein play an important role in hair growth and can be extremely beneficial if you want to help you rest regrow his coat. Plus, look for a blend that`s full of antioxidants.
Some owners dab a little apple cider vinegar onto their dog`s coat with a sponge or even drizzle a cup or two into a warm bath where the pet can soak. The antibacterial properties of apple cider vinegar can support healthy skin, hair follicles, and coat, and help your pet avoid infections that may cause hair loss.
Rich in essential fatty acids, primrose oil has anti-inflammatory qualities; making it great for dogs with allergies, dry skin, dry hair or hair loss.

Q. My dog has dry crusty patches on her skin and she scratches till fur is gone, what can it be?
ANSWER : A. Crusting of the skin, itching and hair loss can all be caused by a number of things, most commonly skin infections (from bacteria, yeast or fungi) or from external parasites. Checking for parasites such as fleas and ticks and then treating them can help the skin. However, if a secondary infection or primary skin infection has occurred (hair loss, redness, itching, hot to the touch or oozing debris) then it is best to have it examined by your local vet. Antibiotics and medicated shampoos will usually help the skin to recover and heal. Until you can get to your vet it is best to prevent your dog from scratching or chewing at the area with the use of an Elizabethan (cone) collar or T-shirt so that she cannot introduce any bacteria into the skin from her tongue or nails.

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.

Q. We have 2 Boston Terrier mix dogs both female, 6 and 7 y/o. They go to the groomer often and we use an oatmeal shampoo. They seem to scratch a lot!
ANSWER : A. An oatmeal or sensitive skin shampoo is best for the delicate coat and skin a dog has. Bostons and other “smushed nose” breeds can often have itchy skin especially around folds and wrinkles where bacteria can grow. Dogs can also get dry skin if they are bathed too often! Giving a bath less often than every two weeks can help the skin and coat return to better health by allowing the natural coat oils to evenly penetrate the skin. In between baths, and for those wrinkly folds, a pet or baby wipe can help keep the skin clean and free of bacteria and yeast that may cause itchiness.
