How to Identify Common Pet Problems ?

The 5 most common causes of bald spots on dogs include allergies, Cushing`s disease, pressure sores, genetics, and infection or infestation.
Hemp is the source of CBD oil, considered as the most effective remedy to various skin conditions of your pet, including hair loss.
Human medications such as Neosporin, hydrocortisone, and Vaseline should NOT be used. Topical creams and ointments tend to cause dogs to lick the area even more, so they should be avoided if possible.
Coconut oil is not toxic, so you don`t have to worry if your pooch licks his skin after you apply it. You can apply it topically once or twice per day until the hair grows back. You can continue using it once the hair grows back to keep your dog`s skin and coat shiny and healthy.
There are numerous ways to get rid of bald spots. In some cases, hair loss medications may help you regrow your hair. Other options include surgery, non-surgical procedures or simply covering them up with the right haircut or styling technique.
Bald Spots in Dogs: Common Causes and Treatments. Allergies are a frequent trigger for hair loss in dogs. Like people, dogs can have an allergic reaction to foods, environmental triggers such as pollen, or to parasites like fleas or mites.
In a study on shaved Labradors, hair took 14.6 weeks to grow back in spring, 14.5 in summer, 13.6 in the fall, and 15.4 in the winter. So the hair may grow back slowest in winter and fastest in the fall, just time to grow their winter coat.
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.
Omega-3 fish oils are one of the most popular recommendations — from vets and owners alike. They`re the powerhouse of Lab skin and coat supplements and provide additional benefits from head to tail, including brain-boosting essential fatty acids DHA and EPA. Fish oil is also easy to give your dog.
The lauric acid in coconut oil has been shown to keep hair healthier than other fatty acids. It can be used to improve the health and appearance of your dog`s fur.
While Vaseline is technically non-toxic for dogs, it does not mean it is 100% safe. If over-ingested (and they will lick) it can cause an upset stomach, which can lead to vomiting or diarrhoea. Vaseline forms a barrier over your dog`s skin trapping in toxins, dirt and bacteria.
Other over-the-counter medications safe to use on canine skin include Neosporin—an antibiotic ointment—and Benadryl cream, a topical pain reliever. “Hydrocortisone cream is usually more effective than Benadryl cream,” says Butzer. “But oral Benadryl can help with reducing inflammation in the affected area.”
Recovery and management of hot spots on dogs

It often takes about a week after treatment begins for a hot spot to dry out and begin to heal. Once a hot spot is dry and no longer oozes, continue to keep the area clean and dry. In about two weeks, your dog`s fur will begin to grow back.

Coconut oil contains healthy fats such as medium chain triglycerides (MCT) that act as a conditioner on dog hair and repair any damage while locking in moisture. Including these healthy fats in your pet`s daily nutrition allows hair follicles to grow stronger from the roots.
Unlike olive oil, coconut oil doesn`t contain a high amount of omega fatty acids. While it does have some, it isn`t enough for your dog to access as many of the benefits as other oils can. Coconut oil also isn`t as easily digested and processed, which may render the few fatty acids that get through less helpful.
Hair loss (alopecia) can affect just your scalp or your entire body, and it can be temporary or permanent. It can be the result of heredity, hormonal changes, medical conditions or a normal part of aging.
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.
Yes, just like humans, stress can trigger alopecia or hair loss in dogs and cats. If your pet suddenly starts to develop bald patches or overall hair thinning, visit your veterinarian to eliminate medical reasons for the hair loss.
An apple cider vinegar bath can help get rid of the mange mites. Mix ½ cup of apple cider vinegar with ½ cup of Borax and warm water. Be sure the Borax is fully dissolved before sponging the mixture on your dog`s skin and coat. Also make sure your dog does not lick the mixture, as ingesting Borax can be harmful.
Olive Oil

Some owners have had success in treating very mild cases of localized mange with olive oil. Just apply a thin layer of the oil to the affected areas of your dog`s skin. The oil may smother any mites present, and it`ll also help to re-moisturize your dog`s skin and quell your dog`s non-stop itchiness.

Another natural remedy to try if your dog has mites, is honey balm! Honey has some pretty impressive properties, including antimicrobial properties. It is also soothing and is a common ingredient for human and pet skin treatments, which is why it`s the perfect ingredient to reach for if your dog has mites.
Shaving your Labrador retriever can cause permanent damage to their coat and also puts them at risk of getting skin burns or skin cancer. The Lab`s coat has several functions and it acts as a protective barrier, keeping the sunrays, dirt, debris, and moisture away from your Lab`s skin and undercoat.
In some cases, such as those caused by infections or allergies, the hair may grow back once the underlying issue is addressed. However, in other cases, such as those caused by immune-mediated diseases, hair loss may be more difficult to manage and may not fully resolve.
Their short, dense, weather-resistant coats should never be clipped or trimmed,” says Marilyn Little, judges` education co-chairperson for the Labrador Retriever Club. Labs will need some basic care. Count on regular brushing, a bath, nail trims, oral care, and ear cleaning.

the most relevant questions and answers related to your specific issue

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. I have a 17 year old cat and he has been shedding a lot the past 3 years. Is there anything I can do. I brush him but he doesn’t like it.
ANSWER : A. Brushing or providing objects that your cat can use to brush himself on (such as a scratching post with a brush attachment) are often the best ways to remove excess hair. If your cat doesn’t like the particular brush you use, you may want to try a different kind, or even use a warm wet washcloth to wipe your cat down with instead. This will help get rid of some loosened hairs without being as “annoying” to your cat. If he is grooming himself a lot, adding in a hairball paste to his food or placing some on his paw will help keep the hair from forming into a ball or becoming problematic as he removes the excess hair himself.

If you are seeing patches of hair loss, or any other signs of illness in addition to excessive shedding, then scheduling a senior wellness exam with your local vet is always best to check for aging-related issues which may be causing hair loss or other symptoms.

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. Vomiting hair balls…resembing a hot dog
ANSWER : A. Hair balls are not normal in dogs, as we think of them being in cats. Hair will most definitely cause full or partial obstructions in dogs, and that’s likely why you’re seeing the vomiting. They don’t digest well and tend to hang around in the stomach until the dog is able to vomit them out. They can certainly get so big that they can’t pass and can’t be vomited, and then they obstruct the dog.

The first thing is to figure out why your dog is consuming hair. Work with your vet to determine if there’s an underlying problem, like parasites or allergies, and then work on resolving that. Hopefully that will resolve the hair consumption.

It’s worth mentioning that occasionally licking and chewing are behavioral problems in dogs, but rule out medical causes first.

Q. My toy Schnauzer has red ears and the top of her nose is red under her hair ,help can ya tell me what I can do or give her

Q. What to do if your puppy has alot of hair loss
ANSWER : A. First thing to do is to try and find out why your puppy is losing hair. Hair loss is a normal thing in dogs but if excessive it could be sign of disease. There are many reason for hair loss in dogs like skin parasites, skin infection, allergic problems, food intolerance or poor diet. You should take your puppy to your vets for clinical examination and treatment, if required.
