Why are scabby hair clumps falling off my dog's back and sides?

I would recommend that Maggie get checked out by the vet. There can be many possible causes for skin flaking like this, including allergies, parasites, and seborrhea. Treatment would be determined on the suspected cause. https://www.petcoach.co/dog/condition/seborrhea/

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.

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!

We commonly see an overgrowth of normal bacteria on the skin cause crusting and scabbing. When this happens around and in the hair follicles, the hair will easily fall out. When a dog has a thick coat, the crusting can spread under the coat and go unnoticed. From your picture, it looks like this area may be over the hip/pelvis. In older dogs, when their bones are more prominent, they will sometimes have areas like that due to lying on harder surfaces. These can become pressure sores, so be sure to keep an eye out for those. I agree that the area does not look irritated, but there is still some brown crusting left, so be sure to monitor the area closely for any spread of the crusting. If the crusting spreads or the skin appears red, be sure to have your vet evaluate the area. Good luck! I hope that was helpful. Thanks for using Petco Pet Education Center, formerly Petcoach.

Great job getting rid of the fleas! Yes, it can be normal to have scabs and hair falling out if there was a flea infestation. I would recommend you bathe your dog with a medicated shampoo like this one every 3-4 days until the skin looks better. It will take a while for the hair to grow back. Use the shampoo as directed on the label. https://www.walmart.com/ip/Veterinary-Formula-Clinical-Care-Medicated-Shampoo-for-Dogs-Cats-Antiseborrheic-Antidandruff-16-0-FL-OZ/207485799 I hope this helps!

Hi there and thank you for using pet coach to address your concern. What you are describing could be due to allergies or a skin infection. I would recommend starting a shampoo such as Douxo PS chlorhexidine combination shampoo and bathe twice weekly. I would also recommend welactin omega 3 fish oil, essential 6 spot on by dermoscent and malacetic conditioning spray. If this does not imprive the current problem or it worsens, i would have a veterinarian look at this for further trestment recommendations. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns. I am also available via consultation if needed.

This presentation is probably due to an allergy, although it could also be infection or mites. First of all, in order to rule out skin parasites, you will need to treat with a high quality flea treatment, then ask the vet to perform a skin scrape - this might reveal an infection or a mite infestation. If all of those came back negative, the next step is to treat the allergy symptomatically and try to discover the cause of the allergy. Three main type of allergies are usually affecting pets: food allergies, flea and parasite related ones and environmental type (allergens coming from trees, pollens, dust etc etc). Some medications can be given by the vet in order to repair any possible skin lesions (like steroids and antibiotics). Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
