My dog's scaly skin piles up; antibiotics didn't help. What's wrong?

It is difficult for me to give you much advice without having more information but I will try my best. His skin may be getting worse due to an idiosyncratic drug reaction. The antibiotics may not be agreeing with him. A change to a different class of antibiotic may be all that is needed. The antibiotic he was prescribed may not be the correct one for this particular bacterial infection (if it is a bacterial infection). A culture and sensitivity of the crusty lesions on the head may need to be done in order to find out what bacteria are there and what antibiotic will be most effective. This may be a fungal skin infection (or yeast) and not a bacterial infection) hence why the antibiotic is not working. Antibiotics do not treat fungus or yeast. In young dogs I would be worried that this is a secondary infection of the skin from mange mites. It can be seen in older dogs as well but it is much more common in youngsters. So, I would have your vet do a skin scraping to check for mites. This could be an autoimmune disorder (like pemphigus). A biopsy of the affected area would be needed for diagnosis. That is all I can come up with right off the top of my head. I hope this helps to give you some things to bring up with your vet. Best wishes!

In most cases these skin infections, called bacterial pyoderma, are allergy-related. The antibiotics will help, but as you've experienced the skin problems will come back if the primary allergic disease isn't controlled. The hydroxyzine Becher took was an antihistamine, and that may have helped control the itchiness, however it sounds to me that he needs something a bit stronger to control the allergies and thus the skin infections. Talk to your vet about using Apoquel or Atopica on him; these are great drugs with minimal side effects that really help allergic dogs.

Poor Ezra, that looks miserable! This could be a number of things, including superficial pyoderma, demodicosis, sarcoptes, yeast dermatitis, and ringworm. It is most likely some sort of infection (whether bacterial, yeast, or parasitic) so I strongly recommend bringing Ezra to the vet. Your vet will be able to determine the cause, and Ezra will likely need prescription medication (antibiotics, antifungals, or anti-parasite, along with possible medicated shampoo) to clear the issue. This is unlikely to improve with anything over the counter, so it is worth having him seen as soon as possible. Additionally, depending on his age, he may have some underlying condition that might be making his skin susceptible to infection, such as allergies or hypothyroidismI hope this helps!

I'm sorry to hear Abe is having skin issues. I would be concerned by the progression of his skin that he may have something more going on in addition to the bacterial infection, such as allergies, a skin parasites (mites or fleas) or a fungal infection. I would recommend he be re-evaluated to determine if something more is going on and additional treatment is needed. Good luck!

Poor guy. You did the right thing by shaving it. But now it looks like he is in need of antibiotics because this is a skin infection, hence the yellow crusting seen there. You will need to take him in to your local vet for a quick skin test to rule out mites and a thyroid test may be applicable as well, depending on his estimated age and physical exam findings. The vet will likely get him started on oral antibiotics to hopefully clear up this skin infection. Also Duoxo shampoo seborrhea may help clear up some of these infected areas. Duoxo shampoo for dogs is often found through online stores. I hope he gets better soon. Best wishes and take care.

Any treatment will depend on the underlying cause. It could be a skin infection or allergic reaction or even an autoimmune condition. An exam with your veterinarian or a veterinary dermatologist would be needed for a definitive diagnosis. You can discuss allergy testing, hydrolyzed diets, food elimination trials as well as antihistamine use with your vet. In the meantime, if your dog is scratching, use an e-collar (cone) to prevent further trauma. Consider adding an essential fatty acid (EFA) supplement to the diet. EFAs can promote a healthy [skin and coat](https://www.petco.com/shop/en/petcostore/category/dog/dog-health-and-wellness/dog-vitamins/dog-skin-and-coat). Choose a good quality fish oil as a source of EFAs. Systemic or topical antibiotics or antifungals can treat bacterial or yeast infection. Allergies can be frustrating to diagnose since they have many causes. Once diagnosed, most allergies can be managed with a combination of medication and diet.

You will first need to determine the type of infection. A recheck with your veterinarian would be recommended. Samples can be submitted for fungal culture as well as for bacterial culture and sensitivity. If it is a fungal infection, your vet can dispense an antifungal. Some of these infections can take weeks t months to resolve. If it is a bacterial infection, the sensitivity panel should determine the most effective antibiotic to use in treatment. Allergies should also be ruled out as an underlying cause. They can be frustrating to diagnose since they have multiple causes (food, environmental, parasites). Discuss allergy testing, food elimination trials, hydrolyzed diets and antihistamine use with your veterinarian. Legally, we are prohibited from recommending a medication in the absence of a physical exam. Any prescription medications will need to come from your vet.
