How to Identify Common Pet Problems ?

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

Flea allergy dermatitis, seasonal allergies or atopy, food allergies, contact dermatitis (e.g., soaps and perfumes), and sarcoptic mange (mites) are some of the most common causes of pruritus in dogs. “Pruritus due to skin disease is one of the most common reasons dog owners seek veterinary care.”
When dog scratching gets out of hand, it is often the result of allergies to food or environmental triggers, including mold and pollen. Dogs may also develop a skin irritation called contact dermatitis when they encounter substances like pesticides or soap. Boredom or anxiety.
It is a symptom caused by dry skin, allergies, parasites, or other underlying conditions. Anxiety and boredom can cause dogs to lick, chew, and bite as a response. Changing your dog`s diet may be the key to stopping obsessive licking behavior. Fatty acid supplements can help ease pain and itching from dry skin.
Although there are a number of other more likely causes of itchiness in your dog, intestinal worms could be one of the potential causes. Behaviours that could link to itchiness caused by the presence of worms include any scratching of the rear end or rubbing or dragging their bottom on the ground.
Although scratching with their feet is the most common way a dog will address skin irritation, they may also choose to bite or lick themselves to try and soothe the irritation. This could be brought on by food allergies, bacterial infections, environmental allergies and plenty of other complications that aren`t fleas.
Examples include dry skin (xerosis), eczema (dermatitis), psoriasis, scabies, parasites, burns, scars, insect bites and hives.
What can you give a dog for severe itching? If your pet has severe itching, it is time to get them to the vet. However, for mild cases, giving them a soothing bath, antihistamines such as diphenhydramine (Benadryl), and an effective next-generation flea medication can all be a good place to start.
Mites are tiny spider-like creatures that can typically only be seen with a microscope, but sometimes they may be visible as tiny orange, black or white dots moving on your dog`s skin.
The most common food allergens in dogs are proteins, especially those from dairy, beef, chicken, chicken eggs, soy, or wheat gluten. Each time a pet eats food containing these substances, the antibodies react with the antigens, and symptoms occur. Virtually any food ingredient can produce an allergy, however.
Otodectes cynotis are surface mites that target your dog`s ears and cause intense itchiness. Ear mites are most often found on puppies as well as dogs who interact with outdoor cats. You might suspect ear mites if: Your dog is constantly scratching at her ears.
Baking Soda becomes thick when mixed with water and it can dry out skin`s rashes. It is also an effective dog itching relief while decreasing inflammation and redness. Apply the mixture or paste to the itchy part and leave it for 20 minutes before rinsing it completely.
If your skin is dehydrated, you may notice itchiness, dullness, under-eye circles, sunken eyes, and/or more noticeable fine lines. Severely dehydrated skin symptoms may include dizziness, dry mouth, lightheadedness and/or weakness.
It`s normal for dogs to scratch an itch occasionally, just like us. But if your dog is licking, scratching, or chewing himself more frequently than usual it may be a sign of an underlying problem. To determine the significance of your dog`s scratching, veterinary dermatologists often use the canine itch scale.
The signs of a skin infection in pets include dry, crusty skin, redness, a sour odour, pustules, hair loss, and itchiness. However, these symptoms can also be attributed to other skin conditions, therefore it is vital to consult your vet for diagnosis.
The short answer is yes, dog food can definitely make a dog itch. This is usually due to a food allergy if the dog food is directly involved. Common allergens include chicken, wheat, beef, oats, dairy, corn and rice. Other reasons why a dog may itch include fleas, ticks, infection, or a reaction to something.
The main difference between dust mite allergy and other causes of itchy skin (dermatitis, dry skin, fleas) is that with dust mite allergy your dog will also have sneezing, runny eyes and nose, a cough, and possible wheezing.
Demodex and Sarcoptes mites live within the skin and are too small to be seen with the naked eye. Ear mites are also so small that it`s unlikely you will be able to see them. Your vet can examine samples under the microscope to look for mites.
Treating Your Home for Dog Mites

Mites can live in the environment for up to several days and may lay eggs in your carpet, upholstery, and clothing. In addition to performing a thorough cleaning, you need to separate your infected dog from the environment to prevent recontamination after you`ve finished cleaning.

Once a week, spray your dog`s fur with the mixture. Although not scientifically proven to get rid of flea, the acidic taste of the vinegar may repel fleas and other parasites. If your dog dislikes being sprayed, dip a washcloth into the mixture and rub your dog`s coat. There is no need to rinse your dog afterward.
The antimicrobial and anti-fungal nature of green tea for dogs helps to treat dandruff caused by mites and other bacteria. Green tea also helps soothe and calm irritated skin thanks to anti-inflammatory properties.
It is important to visit your vet if you suspect that your dog has mites. Your vet will need to examine your dog and possibly perform tests to confirm the diagnosis, and determine whether any secondary problems are present (e.g. a bacterial skin infection).
If you`re living with a sneezing, itchy dog, her bed may be to blame. Dog beds, especially if not regularly washed and replaced, can be a major source of dust mites, which can trigger your dog`s allergy symptoms.
Often in dogs with food sensitivities, proteins from animal or plant-based ingredients in the diet are the cause. Beef, corn, dairy, and wheat are some of the most problematic ingredients. It may seem counterintuitive, but it can take a long time for symptoms of food allergies to become apparent.
What are other foods that commonly trigger allergy symptoms? Despite the belief that grains are a big allergen for dogs, most commonly, dogs are allergic to a type of protein in their diet. The most common culprits are proteins found in chicken, beef, lamb, soy, egg, dairy, and wheat.

Q. My cat is excessively scrstching herself., to the point she has sores. She is strictly an indoor cat. Did have flees been treated for 2 months
ANSWER : A. For every flea you see on your pet, there are 100 more in the environment. Get your pet on a good topical or oral flea control through your vet. In flea control, you get what you pay for. Consider asking your vet for a dose of Capstar. It helps get the problem under control by killing the fleas on the pet starting in five minutes but only lasts for 24 hours.

You need to treat your home environment. If you use a pest control service, tell them you are having a flea problem and they can adjust their treatment. Use a premise spray that also contains an IGR, insect growth regulator. This keeps eggs and larvae from maturing into adults and helps break the life cycle. Also, vacuum EVERY DAY, throwing out the bag or emptying the canister every time into an outside receptacle and spraying the contents with insecticide to kill the fleas you’ve vacuumed up.

Treat your yard too, since fleas are opportunistic and will hop a ride into your home on your pant leg without you knowing it. Concentrate on areas under bushes, in the shade. Fleas are less likely to be located in open sunny areas where it gets hot.

If chemicals are a problem, you can use borax. Sprinkle it into rugs, into corners and under furniture, use a broom to work it into the fibers and let it sit for hours, days even. It won’t hurt you or your pet to have it present. Then vacuum it up, reapply as needed. Food grade diatomaceous earth can be gotten from a health food store and worked into the rugs and corners in the same way as borax. These treatments aren’t as fast and effective as chemical insecticides but they can help.

You might want to consider boarding your pet for the day at your vet, to give you the opportunity to flea bomb your house without having to worry about your pet being exposed. They can bathe your pet and give a dose of Capstar while you treat your home.

Be patient, you may have to repeat these steps multiple times 10-14 days apart to help break the flea life cycle.

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. My dog itchs all the time a codozon shot helps but don’t cure it after a bath she turns red and still itchs I changed dog food that didn’t help no fle
ANSWER : A. Do you live in a region where fleas are prevalent. Where I live the fleas are truly horrible, and I see many animals developing a flea allergy. This usually presents as relentless itching especially at the base of the tail, although it can be all over the body. Often on exam I won’t find a single flea, just red bumps, hair loss and itching. In response, I will start animals on an oral steroid such as prednisone (I think your doctor has administered an injectable steroid), while at the same time bathing the animal and starting on an oral flea preventative such as Comforts which I then re dose at 3 weeks instead of 4. Additionally, the environment needs to be decontaminated- flea bombing the house, vacuuming often and washing bedding on hot. The flea life cycle is short, however, so this needs to be one frequently as they will just continue to hatch in your home. Most importantly, I tell my clients, that any steroid (oral or injectable) does not fix the problem, but rather suppress your dogs reaction to it thereby making them more comfortable. Just the steroid alone changes nothing except giving them a brief break from their symptoms.

Now that I have spoken in depth about flea allergy, there is a potential that it is something else. Food allergies are slow to develop, and slow to change. If you wanted to eliminate a potential food allergy I would switch to a novel protein, limited ingredient diet. For example, lamb as the protein source if your previous food was always chicken or beef, and in a formula with very limited ingredients such as lamb, rice and veggies. A pet store should be able to help you with this. While on this diet they cannot have any additional treats for 1 month, to see if you have eliminated the allergy. From an Eastern Medical perspective, I also recommend novel proteins that are “cool”, such as fish, lamb, or duck while avoiding “warm” foods such as beef, chicken, pork.

Finally, all animals with allergies should be on an Omega 3 supplement. Given regularly, this can help reduce overall inflammation in the body both in the skin, joints, and other tissues. Good for allergies, arthritis and overall health. My dogs are on fish oils, but one of my dogs who is allergic to fish gets flax oil instead. I would be happy to consult with you further, but I hope this helps to some degree.

Q. My dog has bumps on his skin. We have combed with a flea comb, and there aren’t any fleas, but he keeps scratching/biting/licking. What should we do?
ANSWER : A. Sometimes does have red bumps on their skin from flea bites. I would recommend seeing a veterinarian because it could be fleas but it could be something else. Maybe you’re combing with the flea comb incorrectly, are you finding brown dirt like particles? Put that dirt like particles on a white paper towel and put water on it (Without losing the dirt). Smear the dirt and if it turns red that is flea dander. Flea dander is bowel movements from fleas and is digested blood. Your dog could also be suffering from other things such as mange, allergies or something else.

Q. Frontline is not working on my dog, what should I use?
ANSWER : A. Frontline works best if it is given either three days before or three days after bathing your pet as it is absorbed through the skin. Frontline works on pets, but you will need to continually give treatment for up to three months before the environment and your pet are fully flea-free. Your pet can continue to get fleas from the environment as the eggs hatch and attempt to jump on your pet. Making sure to clean the area your pet is in, such as washing bedding and vacuuming carpeting (especially areas with cracks such as along the wall) can also accelerate flea removal. If your pet still has fleas and you want immediate relief, your vet can provide you with an oral medication such as capstar to kill fleas depending on when the last Frontline dose was given.

Pets can continue to itch for a while even after the fleas themselves are treated. Flea bites can cause an allergy, called flea allergy dermatitis, which can cause itching, scratching and redness on the skin. While many owners think this means fleas are still there, it could just be the skin healing from bites. An allergy medication and preventing your pet from scratching can provide relief during the healing process.
