That sounds like a herpes infection of the ears
it could be mites eating the fur
This could be an allergy. It could be parasites besides fleas. A vet check can answer this question for sure.
No. Fleas themselves cannot have fleas, but they can have these things called "mites".
scabs are not "just" dried blood, they're formed by a chemical reaction, mainly of polimerized proteins and are quit water proof.
Puppies can get scabs on their heads due to various reasons such as allergies, skin infections, parasites like fleas or mites, or injuries from scratching or playing rough. It's important to consult a veterinarian to determine the exact cause and provide appropriate treatment for your puppy.
its a obsessive and a habit to all human beings...well some
The clear liquid that sometimes oozes from skin scabs is primarily a combination of serum, which is the liquid part of blood, and lymph fluid. This fluid contains proteins, antibodies, and nutrients that help in the healing process by providing moisture and facilitating the delivery of immune cells to the site of injury. It's a normal part of the body's repair mechanism, signaling that the skin is recovering.
Chickens can develop scabs for several reasons. Picking by other members of the flock can draw blood which scabs over, if this is the case you will notice some moderate loss of feathers. Your chickens can also have insect infestation. Mites and barn fleas, deerflies and gnats can and will draw blood or bite and irritate the bird to the point they will peck at themselves. A good dusting with commercial mite control once or twice per year will remedy this problem.
The cat may have fleas. Check by collecting some scurf from its coat on a piece of white paper. Dampen the scurf slightly, if any of it turns reddish, the cat has fleas. I don't know of a home remedy. Ask in the drugstore or, better still, ask a vet. If it's not fleas the cat might have ringworm. This needs professional treatment. Skin allergy to flea faeces may be the cause of persistent scratching which can result in bleeding and the formation of scabs. A good quality tubed-ointment type flea-killer applied once per month to the nape of the neck has been known to effect an almost overnight cure from this very distressing condition.
Fleas can indeed infest short-haired dogs. Fleas can live on dogs of any hair length or hair color. They can also infest many other types of animals, including cats, ferrets, rabbits, and rodents. Fleas are external parasites that bite and feed on the blood of animals. They are also capable of biting and feeding off of the blood of people. These parasites are problematic because they can cause a variety of illnesses for both animals and people. Many animals are allergic to fleas and the resulting skin disease can be painful for them. In addition, fleas can cause localized areas of hair loss, inflammation and scabs known as "hot spots". Tapeworms can be carried by fleas and passed to animals that become infested with fleas. Fleas also play a pivotal role in the transmission of diseases such as plague and cat scratch disease.
because when you bleed the blood hardens and turns into scabs
Scabs near a dog's anus and surrounding area could be due to various reasons such as flea allergies, anal gland issues, skin infections, or even trauma from excessive licking or scooting. It's best to have your veterinarian examine your dog to determine the underlying cause and provide appropriate treatment.
