My dog has red, itchy bumps spreading all over. Is it mange or fleas?

Updated On September 23rd, 2025

Pet's info: Dog | Dachshund | Male | unneutered | 3 months and 21 days old | 4 lbs

Louie has had these red heat looking bumps that started out in a few spots on his inner back legs. When I first saw it I instantly thought either heat bumps or fleas so I treated him for fleas. (Walmart brand) then I notice they did not go away so when I bathed him I started using baby shampoo because I thought maybe the other shampoo dried his skin out. Now all of a sudden they have spread all over his body even his eyes. Is this mange? It itches really bad you can see the scabs from him biting

Poor Louie! Yes, it is possible this is mange. It’s still possible this is fleas as well. Flea products that you can buy over the counter do not work as well as flea products from the veterinarian. Also, only use pet shampoo. Dogs have a different skin ph and our shampoos can dry out their skin. Lastly, Louie needs to see his veterinarian. I bet that rash is uncomfortable. He will need medications to clear it up. The doctor can also test him for mites. I hope this is helpful and please feel free to post any additional questions.

    Hi there. Yes, from what I can see in the second photo, that does look like a squashed flea. :) The red/brown spots on the skin and excessive chewing are common to see with fleas, also. I would recommend getting Louie (as well as your other dog) started on an oral flea/tick medication such as Nexgard or Bravecto. These meds are safe and very effective, and can be purchased from your veterinarian or ordered online with a prescription from your vet. If your pup is feeling itchy in the meantime, you can try bathing him in an aloe and oatmeal dog shampoo to help soothe his skin and make him a bit more comfortable until you can get the fleas treated. I do not recommend using any kind of flea/tick shampoo or over-the-counter topical flea med such as Adams, Sergeants, etc. as these can be toxic and cause severe reactions in some dogs.

Hello, this morning we found what might have been a flea in our dogs fur. We have noticed these on his stomach and there are some on his legs as well. We just figured he was chewing at it because he’s a puppy or our other dog might have been playing

Hi .. I am not sure what this rash is on my dog . We had a flea issue which has gotten a lot better . He is always scratching and biting. The rash is on his inner thighs and under armpits , a little on his stomach . I found a “hotspot” on the out sid
Unfortunately, you can’t tell the cause of the rash just by looks alone. It’s possible this is still related to the fleas in the environment or that this is an allergic reaction. This could be a mange as well. I recommend to treat him with a good flea product like Simparica. If you must use an over-the-counter product, use Frontline. This is still a good product but there are some resistance with fleas. Make sure to protect the area from any licking or scratching with an Elizabethan collar. You can wash the area once a day and rinse it well. Start him on an omega-3 fatty acid supplement. If this does not start to look better within a week or if it starts to get worse, have him examined by the veterinarian. I hope this helps and please feel free to post any additional questions.

Itchy skin and red bumps like this are often due to one of the following things: 1) Allergies - this can happen suddenly and is usually due to an environmental (i.e pollen) cause. Below is a link to more information about allergies. https://www.petcoach.co/article/how-to-tell-if-your-pet-has-allergies/ 2) External parasites - fleas, lice and mites can all cause intense itching. It's good that he was treated for fleas, but I would ensure they are all gone and give treatment if needed. 3) Over-bathing, or using the wrong product for bathing - Bathing too often can cause the skin to get dry and irritated. Dogs should normally be bathed no more than once a month with a shampoo that is labeled for dogs. If you bathe more than that, or use a shampoo, soap, or other product that is meant for people, then you could be damaging the normal protective barrier of the skin. One thing you can do for itchy skin, is give a bath with cool water using an oatmeal or aloe shampoo. You can g

uncontrollable itching, red spots on thighs...mange?
It is quite possible. Other causes for itching and red spots could include fleas, lice, infections (bacterial or yeast), ringworm, allergies, among others. I would recommend that you have Rudie examined by a vet and have a skin scraping done to look for mites. Then he can receive appropriate treatment.

My dog has small lumps under the skin on his neck that seem to be dispersist to other areas causing small round bald patches with scabs in them. It's as though something is biting him.
Poor Ginge! It is possible that he has an allergy to fleas, ringworm or mange causing his skin lesions. These lesions can become infected if he is scratching himself. Make sure that Ginge is receiving a high quality flea and tick preventative, such as Nexgard, Bravecto or K9 Advantix II regularly. You can also try bathing him in either a gentle oatmeal-based dog shampoo or medicated antiseptic shampoo (drsfostersmith.com/product/prod_display.cfm?pcatid=27982) to determine if there is any improvement in his skin. If these lesions continue or worsen, Ginge will need to go to his vet for further evaluation. I hope this helps and that all goes well! Please excuse the double answer.

My French bulldog is 1 year and he has been shedding a lot. We took him to the vet couple of times and they gave us shampoo and antibiotic but it's not enough, the medicine didn't work and he still sheds. The PROBLEM is that he has these small little
Thank you for posting your question. I see Otis is a 1yr old French Bulldog and the pictures seem to show several red bumps on his abdomen. Where I practice we do see quite a few French bulldogs with environmental allergies. However, that being said there are multiple causes for the bumps that you are seeing. One possible explanation could be a simple environmental allergy. I see that your veterinarian had started Otis on topical shampoo therapy along with oral antibiotics. This is a good approach, and sometimes this can take some time to get results for the problem to resolve. It does appear based on your pictures that Otis may have a skin infection. The topical shampoo and antibiotics will typically treat this. However, sometimes you have to switch to a different antibiotic and shampoo if it has not resolved with the instructed course of treatment. Also, being 1yr old, skin mites such as demodex and Sarcoptic mange (as you have already mentioned) may also be the culprit. If a skin sc

Lou is adorable! Unfortunately Frenchies are notorious for developing both environmental allergies (atopy) and food allergies. These signs can be especially apparent during seasonal weather changes. Other issues, like secondary bacterial or mite infections could be causing hair loss. It would be best to have Lou examined by a veterinarian to evaluate for infection and to prescribe medications to help relieve the itch. There are newer, safer medications available for allergies like Cytopoint that have been proven very successful. Lou may need a medicated shampoo or even oral anti- fungal or antibiotics is infection is present. Until you can get to your veterinarian you can try bathing with a soothing shampoo like Douxo Calm to provide some relief for Lou. Thanks for using Boop by Petco and I hope Lou is feeling better soon!

My dog is scratching a lot , he also nibbled at his back and paws. Could there be a real serious issue? I also noticed raised hair bumps on his snout.
It doesn't sound too serious. What is sounds like is fleas. If you don't have him on a good flea prevention (like Advantage II or Bravecto, etc) then I would suggest you start him on one ASAP. https://www.walmart.com/ip/Advantage-II-Flea-and-Tick-Monthly-Treatment-For-Extra-Large-Dogs-4-Treatments/37601740 You may also consider bathing him in this anti-itch shampoo. I would not use a flea shampoo as they are rarely work and if they do work they are a very temporary fix. https://www.walmart.com/ip/Veterinary-Formula-Clinical-Care-Hot-Spot-and-Itch-Relief-Medicated-Shampoo-for-Dogs-and-Cats-16-fl-oz/24885757 Hope this helps.

Those spots on Blue could be several things including fleas, allergies, skin mites, bacterial infection or ringworm (which humans can get). There are a couple things you can do at home and they can help but they may not address the underlying cause. 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 lesion once a day (not his whole body, just the lesions). Also protect the area from trauma by having your pup wear an elizabethan collar at all times. If the lesions do not start improving within a week or if they are getting worse, have him examined by the veterinarian. I hope this helps and please feel free to post any additional questions.

Hunter has had these red bumps for about 2 days. Doesn’t seem to bother him, I’ve tried home remedies to calm them down as far as oatmeal bath, apple cider vinegar nothing seems to help it. I’ve also looked for ticks and fleas don’t seem to see any
This 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.
