My dog has scabs, no fleas. Could it be fleas despite preventative?

This could be an infected fleabite. Unfortunately fleas only hop on the body of your pet when they want to feed, then they hop off again and stay in your pet's environment. So you need to treat all pets in the household as well as the environment (which contains the fleas, their eggs and larvae). Flea treatment:  1) Get some flea medication such as a Flea spray or a spot on from a pet shop or your veterinarian and apply monthly 2) get flea powder, put some in your vacuum cleaner bag and vacuum your house and furniture and also non-carpeted areas frequently to remove flea larvae and eggs which live off house dust., Dispose of the bag in the trash outside. Hot-wash all the pet's bedding, If you do this diligently for a few months you will get rid of the fleas. Flea products: Spot-ons and/or chews Advantage, Advantix Advantage Multi (Advocate in the UK) Frontline (ticks as well) Bravecto spot on (ticks as well) - for cats, in tablet form for dogs Simparica, Nexgard Revolution (stronghold in the UK) Tablets: comfortis (will only kill fleas once) Collar: Seresto (ticks as well) House spray: Indorex

High quality flea preventatives are very effective, so I would be surprised if your dog is itching from fleas. Different flea preventatives utilize different mechanisms of action to kill fleas. Some preventatives work by killing the flea after it bites, so it is not unheard of to see one rare flea. The important part is that the flea is killed before it has a chance to reproduce and lay eggs. The next time you see dirt on your dog, try to put it onto a white paper towel and moisten it slightly. Flea dirt becomes a reddish-brown color when wet. If you do not notice a significant color change, it is just regular dirt. The dandruff may be appearing as a result of skin sloughing when your dog itches. Allergies to a wide variety of environmental influences and food are a common cause of itching in dogs. Consider discussing this intense itching with your vet because dogs can develop skin infections by introducing bacteria or yeast from excessive scratching.

The symptoms you have described are pretty classic for Flea Allergy Dermatitis (FAD). Some dogs are actually allergic to flea bites, similar to how some humans react to mosquito bites and some aren't bothered by them. The best way to treat this is to get rid of the fleas using a good-quality monthly flea preventative. The most effective preventatives are prescription from a vet. Lila may also need antibiotics or anti-inflammatories to treat the skin while the fleas go away (which takes 12 weeks since the fleas have laid eggs in the environment that will hatch later). https://www.petcoach.co/article/flea-allergy-dermatitis-or-flea-bite-hypersensitivity/

Hello there! These could be flea bites for sure, although less likely if he is on a preventative, especially if it is the type of preventative that kills adult fleas, as well as stopping fleas from reproducing. This could be many other types of rash, as well, though, such as a bacterial rash, or even a form a bruising which occurs when the blood platelets are low. It is always a good idea to get a check up done with your vet, to be sure that there is nothing to worry about! Best of luck!

If your dog is on a high quality flea preventative (Nexgard, Bravecto, Advantix) every month, I would be very surprised if there are any flea eggs. If you look closely at your dog's hair coat, flea eggs resemble a grain of salt and are often confused with dry skin flakes. If fleas are present, you would be more likely to see adult fleas or flea "dirt" (feces). Flea dirt looks like a fleck of pepper and turns reddish brown when moistened with water on a damp paper towel. Flea eggs could be transferred to clothing by direct contact, but they would not be able to grow and reproduce without a warm blooded host, such as a dog or cat.

This is probably caused by an allergic reaction. first of all make sure you de-flea Sammy regularly every month with a high quality spot on (ex. Advantage) as fleas are by far the most common reason for these reactions. If the fleas are not the problem, it could be an allergic reaction to food or an environmental factor. this is more complicated to treat and will sometimes require medications such as Steroids, anti histamines or Apoquel in order to stop the allergy.

It is hard to say what is causing Bacardi's problems. The third picture you included looks like pus, which would indicate infection and would need antibiotics to treat. Some dogs can be allergic to fleas, and it may only take 1 bite to make them itchy all over. If you are seeing scabs from where you applied a flea medication or flea collar, it may be irritating the skin so I would recommend removing it and bathing with dog shampoo thoroughly. Causes of itching in dogs include fleas or flea allergies, mites, or skin infection. The hair in the second picture looks like normal shedding to me, but if you feel it is weird for Bacardi, it could be caused by inflammation or from the extra itching she is doing right now. You can try a shampoo like Dechra MalAcetic Ultra Shampoo, but if it doesn't respond in a day or two, Bacardi should be seen by a vet as she may need oral medications to control the itching.
