Why is my boxer losing fur with bumps and flaky skin on her spine?

Thanks for using Petco Pet Education Center, formerly Petcoach! This is likely due to an allergic reaction. I recommend that you have him evaluated by a veterinarian. If this is confirmed, they would likely start him on anti-histamine medications and steroids which can help with an allergic reaction. Best of luck!

Poor Princess! That definitely sounds uncomfortable. These lesions can be caused by a skin infection, skin mites, certain cancers, food allergies, or even some autoimmune diseases. This is a very broad list, and can be narrowed down with a vet examination. Your vet may take some small samples from Princess’s skin and some bloodwork to determine what is going on and start the appropriate treatment. I am happy to answer any other questions you may have or look at pictures of your dog’s skin!

The bumps are not anything I would be overly concerned with - they are like pimples. I suggest you wipe the area daily with these medicated wipes. ( https://www.allivet.com/p-8105-preva-medicated-wipes-120-ct.aspx ) As for the vaginitis, it usually goes away on it's own once they have had their first heat or are spayed. If you were wanting to breed her then you may have issues since she has a resistant E.coli. That may keep her from conceiving. The other reason for chronic vaginitis can be due to abnormal vulvar conformation. If the vulva is inverted then this could be the problem. This can be corrected with surgery.

It could be a pyoderma (skin infection). See your veterinarian for an exam. He or she may diagnose bacterial or fungal skin infection and can prescribe the appropriate medication afterwards. Treatment may be topical, systemic or a combination. Consider adding an essential fatty acid supplement, such as DermCaps or EicosaCaps, to her diet to promote healthy skin and coat. Place an e-collar (cone) on your dog if she is licking or chewing excessively.

I can see how red Barbie's belly is, as well as some marks where she has been scratching herself. She also has some red bumps, which can be a sign of a bacterial or fungal infection, as well as certain types of skin mites. Certain hormonal imbalances such as Cushing's disease (an overproduction of steroids by the body), and food allergies can cause signs like this as well. I recommend having Barbie seen by a vet soon to determine the cause and any underlying conditions. A vet will be able to determine the appropriate treatment and prescribe any antibiotics or medicated shampoos that will treat this issue. I hope this helps and would be happy to answer any questions you may have!

This does not sound like a normal thing to happen in dogs, and I recommend that Binky see a vet for her skin issue. Your vet may do a skin scrape to look for mites, skin cytology to look for bacteria or yeast under a microscope, or bacterial or fungal cultures may be needed. Possible causes for bumps include fleas, mange, lice, infections (bacterial or yeast), ringworm, allergies, among others. I would recommend that Binky be on year-round flea prevention. While you await for your appointment, you can try a medicated shampoo like Dechra MalAcetic Ultra Shampoo, but be careful not to get it into her eyes. Also, think of any changes that have happened in the last few weeks, like changes in food, treats, medications, supplements, or household cleaners that could have had an effect on her skin.

The bald spots and pimples may indicate minor infection or may be a symptom of a broader underlying condition. Skin problems can have a variety of causes, sometimes more than one. It is important to have the condition addressed by your veterinarian to determine if there is a medical cause for your pet’s skin issues and treat accordingly. Young dogs can get skin infections, commonly referred to as 'puppy pyoderma'. This usually occurs on the belly and inside the hind legs. This type of infection usually resolves without treatment as the puppy gets older. [*Staph* infections](https://www.petcoach.co/dog/condition/staphylococcal-pyoderma-1/) are common in dogs of all ages and may requires antibiotic therapy to treat. In pets of all ages, [fleas](https://www.petcoach.co/dog/condition/flea-allergy/), [food allergies](https://www.petcoach.co/dog/condition/food-allergies/) and [environmental allergies](https://www.petcoach.co/article/food-allergies-vs-environmental-allergies-whats-the-difference) (contact or inhaled) can be a cause. Any one of these may not be enough to trigger the breakouts, depending on how sensitive your pet is, but a combination can be enough to start the itch-scratch cycle. Finding out the cause and eliminating it is the best course of action. With flea allergies, if your pet is sensitive enough, a single bite can cause them to break out scratch enough to tear their skin or cause a [hot spot](https://www.petcoach.co/dog/condition/hot-spots/). Diagnosing the cause of allergies may require [allergy testing](https://www.petcoach.co/article/allergy-testing-immunotherapy-in-dogs) and [food elimination trials](https://www.petcoach.co/article/food-trials-for-allergies-in-pets-what-to-expect). [Check for fleas](https://www.petcoach.co/article/how-to-check-your-pet-for-fleas-and-ticks) with a flea comb. Look for fleas and/or tiny black granules, like coarse black pepper. This is flea feces, consisting of digested, dried blood. You may find tiny white particles, like salt, which are the flea eggs. Applying a good topical monthly flea treatment and aggressively treating your house and yard will help break the flea life cycle. If you use plastic bowls, this is a possible cause for hair loss, though this tends to be on the chin, where their skin touches the bowl while they eat. If you suspect this to be the culprit, try changing the bowls to glass, metal or ceramic.
