My dog has dot scabs. Could it be fleas spreading, even if I see none?

Why take the chance? just treat your dog with a high quality flea preventive treatment and then you can rule out fleas, that is the only way to rule it out completely as fleas and eggs can be missed by the naked eye.

These scabs could be due to itching from something such as fleas, mites, ringworm, or allergies. If he isn't up to date on his flea treatment, I can give you one for him. First, I would give him Capstar. It's a one time pill that starts killing fleas within 30 minutes. Then follow up with a spot on treatment, such as Advantage or Revolution. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash his bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. If he is up to date on his flea treatment, I recommend taking him into the vet for an exam today or tomorrow. The vet can do blood tests, skin scrapings, and use a Wood's lamp to diagnose allergies, mites, and ringworm. Once the cause of the itching is found, the vet can prescribe the appropriate treatment. I hope this helps!

Unfortunately fleas do not live on the dog, but only hop on to feed and then they hop off and stay in his environment (your apartment!) until it is time to feed again. 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 (which you have done already) 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.

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/

This could indeed be a flea infestation, even though you cannot find fleas. It could also be allergies. Best to rule out fleas first and here is a good way to do so: 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).

Poor Dash! Trifexis is generally a very good flea prevention so flea bites are not likely. Those spots could be several things including allergies, skin mites or a bacterial infection. You can try adding in an omega 3 fatty acid supplement for dogs, this can help improve the skin health. You may also try changing his diet to something like Royal Canin or Nutro as they are aimed at skin health. You can wash the lesions with soap once a day and rinse well (don't wash his whole body, just those spots). Protect the areas from licking or scratching. If they don't start looking better within about a week or if they get worse, have him examined by his veterinarian who may prescribe medications. Best of luck and please feel free to post any additional questions.

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.
