You might be able to tell if your dog has mites by carefully studying their skin. If they`re scratching, biting, or chewing themselves excessively you might suspect they have mites, and take a closer look. Your vet, however, is the best person to diagnose mites in your dog.
Demodex mites tend to cause problems around the eyes and feet but in severe cases can spread across the whole body.
Mange is caused by microscopic mites that invade the skin of otherwise healthy animals. The mites cause irritation of the skin, resulting in itching, hair loss, and inflammation.
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.
Like their relatives, the ticks, mites pass through four stages of development: egg to larva to nymph to adult. All stages have eight legs except the six-legged larva.
NexGard® and NexGard SPECTRA® are highly effective options to treat mites on dogs. They treat and control Sarcoptes mites, Demodex mites and ear mites. NexGard SPECTRA: The most complete protection against fleas, ticks, mites, heartworm and intestinal worms, all in one tasty chew.
What do mites look like on a dog`s skin? Mites look like small spider-like creatures, with are estimated to only be 1/4 to 1/3 millimeters long. To the naked eye, they may look like tiny black dots on the skin, so you can only really see them under a microscope.
Treatment of Demodex in Dogs

Anti-mite creams can be used as well as anti-inflammatory creams and corticosteroid creams. Your veterinarian may also recommend using benzoyl peroxide on larger areas. Your veterinarian will probably trim the hair around the affected areas.

The mite burrows in the skin and makes the dog itch. The itching is VERY intense and may be worse at night. Red pimples, crusts and hair loss are seen, especially on the ears, elbows, hocks and chest as the disease progresses. The scabies mite can infest people and burrow into their skin.
Canine scabies is highly contagious. Transmission occurs through direct contact with a carrier animal, or when a mite falls off the skin of a carrier and survives in the environment long enough for it to infest a new host animal. At 50 – 59 F, mites can survive between four to 21 days in the environment without a host.
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.
Dry, flaky skin can be a sign of parasites that cause mange, such as the Demodex mite, canine scabies, and cheyletiellosis (Walking Dandruff), or it could indicate that your dog has lice.
Unfortunately, your bed is probably where you`ll find the highest concentration of mites. Like the common bed bug, mites love to make their homes in mattress pads and pillows. You can protect yourself against mites by enclosing mattresses and pillows in dust-proof covers.
They usually come out at night to feast on dead skin cells before retreating to their hiding spots to lay eggs.
Use a steam cleaner to heat treat your carpeting, furniture and bedding. Wash the bed spreads and your clothing and other such fabrics in hot water and dry clean them at a high temperature. If mites are on you, take a hot shower with some medicated shampoo.
Essential oils contain compounds that repel or kill insects, including dust mites. The best essential oils for getting rid of dust mites are clove, rosemary, and eucalyptus oil. Add 20 drops of oil to four ounces of witch hazel, and spray your mattress, couch, drapes, and other dust mite hangouts.
Your doctor has several ways to find out if eyelash mites are causing your symptoms. A special microscope with a bright light called a slit lamp can show if: Tube-like dandruff is at the root of your eyelashes. Mites, or their eggs or babies, are on a few eyelashes taken from your eyelid.
Symptoms include red or dry eyes, swollen eyelids, sticky lashes, itching, burning or stinging, grittiness in the eyes and crustiness around the outer edge of the eyelid. An infestation of mites can also cause dry and itchy skin, and it can even damage the oil glands at the edges of the eyelids and the lashes.
Dust mites can be difficult to detect due to their small size. These microscopic arthropods are estimated to be only 1/4 to 1/3 millimeters long. You can only see them under a microscope, and even then, they only look like small white spider-like creatures.
Mites are barely visible to the human eye, which means it`s hard to notice them until there is a large infestation. There are many different types of mites, including dust mites, furniture mites and flour mites.
Fleas, allergies, dry skin, insect stings – even boredom and anxiety can all cause intense scratching. Don`t wait until the area is raw. Check your dog`s chin and neck to see if anything seems peculiar. If it`s nothing you can remove right away, such as an insect or a twig, give your vet a call.
Some dogs may be more prone to mite infestations due to underlying health conditions, stress, or other factors such as malnutrition. Because mites can be passed on indirectly, keeping your dog`s environment clean is essential.
Although they can transfer from animals to humans and vice versa, several types of scabies mites exist, each having a preferred host species on which it reproduces. In dogs, scabies mites cause mange. Scabies is the most common and important condition resulting from mite infestation of humans.
What`s That Smell? Dogs with sarcoptic mange often smell bad — not because of the mites themselves, but because bacteria and yeast take advantage of the situation. Mangy dogs will develop a strong, musty, unpleasant odor – with a particularly foul smell coming from their ears.

Q. One eye is more red than the other. Last night he was pawing at it,today, he isn’t. Should I bring him to the vet?
ANSWER : A. Sounds possible that he had some irritation to the eye that is at least not itchy anymore. You can do either, having it checked now to confirm mild irritation, potentially due to debris or a topical irritant to the eye; or you can flush the eye with sterile saline eye wash (over the counter) using care not to poke or prod the eye and see if the irritation goes away on its own within the next 24 hrs. It has shown improvement already it appears, however if it is not cleared up and your pet seems irritated by it AT ALL, then it should be looked at by a vet and tested for a possible corneal scratch or ulcer. These can cause redness of the eye, eye discharge and pawing at the face. They are usually treated by prescription only topical eye antibiotic ointment and generally do very well after treatment.

Q. Weak, discharge from eyes, swelling on right eye, does not want to open eyes. What is wrong?
ANSWER : A. If the discharge from the eye is green or yellow in color, it can indicate a secondary infection. Swollen eyes can be caused by a number of things ranging from allergies to infections, to injury to the eye itself or surrounding areas.

It is best to have your pet’s eye examined by your local vet. They will most likely wish to place a stain in the eye that can check for damage such as cuts or scratches. An ointment can then be given to help reduce inflammation, pain and take care of infection.

Until you can get to the vet, be sure to not let your pet scratch or paw at their eye as this can make things worse. You can also use a warm wet washcloth to gently remove any debris and allow the eye to open some, providing relief. However, if symptoms worsen, or the swelling travels to the face, head or neck, it may indicate a serious allergic reaction which should be treated immediately.

Q. My dog got into a fight with a cat. I think the cat scratch her eye. I clean it out with water. I have gentak can I put that in there?
ANSWER : A. It is best NOT to place anything in the eye unless specifically instructed to do so by your vet as it can cause more damage to the eye. As cat scratches and bites can easily become infected and the eye is a very sensitive area, it is best to schedule a veterinary appointment as soon as possible to have the eye examined. Your vet can place a fluorescent stain in the eye to check the extent of the damage and can then give you a pet-safe medication to place in it as needed to help it heal. Until you can get to the vet, it is best to keep the eye clean of debris and discharge with a warm wet washcloth, and to prevent your dog from scratching or clawing at the eye with the use of an Elizabethan (cone) collar.

Q. My cat continues to scratch on furniture and carpets. He has plenty of scratching posts around the house. Please help!
ANSWER : A. Scratching is a natural behavior in cats that can be frequently frustrating for pet owners who want to keep their furniture from being shredded on a constant basis. The texture of furniture and carpet is very appealing to cats and this why they frequently choose to spend their time on this activity as opposed to playing with their own cat toys. Here are some suggestions to help curb this unwanted behavior:

1. Purchase a cat scratching post or cat tree that is covered in carpeted or textured material. Place it in an appealing spot that your cat would be inclined to spend time (eg. in the sun). You can also place catnip on the scratching post or cat tree to make your cat even more interested in the new object.

2. You can utilize double sided tape on the ends of the furniture because you cat will not like the sticky feeling and will learn to not scratch in that region. Use the tape that has a lighter adhesive in order to prevent any permanent damage. Other materials, such as aluminum foil or bubble wrap can also be placed on the furniture to discourage the scratching.

3. Keep nails trimmed short by either learning to do this on your own at home or using a veterinary technician, or groomer. Nails can usually be trimmed every 6-8 weeks.

4. Redirect the unwanted behavior. If your cat begins scratching, use a favorite or new toy to distract the cat from the scratching. Give your cat positive praise for not scratching.

5. As a last resort you can use a spray bottle full of water to spritz your cat when he or she is scratching inappropriately at your furniture. Generally, cats do not like water and this will discourage them from continuing the behavior.

Have patience with your cat because it can takes time to understand this is an unwanted behavior and that furniture is not another toy for them to use. You can always consult your veterinary or veterinary behaviorist to help with ideas or further solutions to this problem.

Q. I was told by my vet that my dogs cherry eye was caused by something hitting his eye when he was poking around under a bush. I was told surgery needed
ANSWER : A. Prolapsed gland of the eyelid refers to a pink mass protruding from the animal’s eyelid; it is also called a “cherry eye.” Normally, the gland is anchored by an attachment made up of fibrous material. The most common sign of “cherry eye” is an oval mass protruding from the dogs’s third eyelid. It can occur in one or both eyes, and may be accompanied by swelling and irritation. He may have acquired it by getting an injury to his eye but this isn’t the case sometimes. Sometimes there is a weakness in the fibrous attachment.

The veterinarian will review the mass in the dog’s third eyelid and determine if there is an underlying cause for the condition. The diagnosis of the prolapsed gland could be scrolled or everted cartilage in the third eyelid, abnormal cells in the third eye, or a prolapse of fat in the dog’s eye.

Treatment often includes surgical replacement of the gland in the dog’s eye, or removal of the entire gland if the condition is severe. Conversely, if medications are recommended, they are typically topical anti-inflammatory drugs that are effective in reducing swelling.

Q. What can be given to dogs to stop the brown draining around dogs eyes? I was told tetracycline would work.
Thanks
ANSWER : A. Eye leakage is normal in some breeds of dogs, especially those that are more “bug-eyed” types. This eye leakage is just normal tears coming from the eye which can stain lighter colored coats. Unless there is an infection it does not need to be treated with antibiotics. Signs of infection usually include drainage that is thick or goopy and is yellow or greenish in color. Dogs with infections may also want to keep the eye closed, or may paw and scratch at it.

For plain tear-staining. Tear-stain wipes can be used around the eyes to remove the stain and bring the coat back to natural color. If infection is suspected, it is best to have your vet take a look at the eye prior to placing any medications in it.

Q. My 14 week old English bulldog has what looks like a small pimple on the outside corner of her eye . It appears to be completely external. What to do.
ANSWER : A. If the pimple is not bothersome it may be best to just keep an eye on it and watch for any changes such as reddening, growth, or itching/pain to your pup. Puppies can sometimes get strange bumps that may go away over time. If the pimple grows in size, becomes very red, affects the eye itself or is bothersome to your pup then it is best to have the vet take a look. They can safely remove the growth if needed, and may also recommend additional treatments to protect the eye. If your pup is bothered, placing an Elizabethan (cone) collar on her to prevent scratching at and possibly hurting the eye is best until she can get into your vet.

Q. My pet is suffering eyes discharge, what should I do?
ANSWER : A. Mucus, yellow-green pus, or a watery eye discharge can all be signs of conjunctivitis, which is inflammation of the lining of your dog’s eye.

There is a wide range of causes for conjunctivitis, from allergies, injury, birth defects, and tear duct problems, to foreign bodies, dry eye syndrome, infections or even tumors.

Other signs of conjunctivitis include excessive blinking or keeping the eye closed, squinting and pawing at the eyes.

Treatment of this condition depends on the underlying cause. In most of the cases cleaning, soothing the eye and applying antibiotics eye drops suffice but is some instances further investigation is required to establish the cause of the excessive eye discharge, and this should be performed by a veterinarian.
