What's this rash on my new puppy's elbow? Is it Demodex or ringworm?

Poor guy. I would highly recommend asking your vet to perform a skin scrape on Tombo. These lesions are suspicious for possible demodexx mites. The trumectin is a Demodexx treatment; however, you didn't mention that your vet actually tested for this. If this is a mite problem, then a topical medicated shampoo can be used in conjunction with the injections to gain better control of the overpopulation of mites on the skin. Also there are several other products that treat for mites that may be more effective for him, such as the off-label use of Nexgard, Bravecto or Simparica (have to be 6 months or older, so this may be an option depending on his exact birthdate). Also a skin culture should be done to determine which antibiotic will get rid of this infection for a certainty. Most skin infections will respond to broad spectrum antiobitcs, but there can be resistant infections that don't respond, which may be the case with your pet Tombo. This infection doesn't look particularly fungal in nature; however, if your vet already did a skin impression to confirm there is yeast present on the skin, then definitely continue with the Fluconazole treatment as prescribed. These viable tests (skin culture, skin scrape, impression) should give us a good idea on how we should be treating him from here moving forward. As a general rule of thumb, you can give you pet pet formulated fish oils for just about any skin condition in which the skin is red. Fish oils act as a natural anti-inflammatory and can also held with overall skin health. You can find these at your local pet store or through your vet office. I would also inquire with your vet about prescribing some antihistamines to help with any itching that Tombo has right now. That will help him allow his skin to heal and respond to all the treatments he is receiving. I hope this helps you find some resolve for Tombo's itchy/irritate and balding skin. Best wishes and take care!

Those look like pyoderma/bacterial skin infection erythematous (red) collarettes. The treatment is typically a 10 day course of prescription Simplicef (cefpodoxime) oral antibiotic, a medicated antibacterial/antifungal shampoo such as Malaseb (available on chewy.com or petco.com) every 2-3 days for 2 weeks and a topical prescription antibiotic/steroid ointment such as Dermavet. Your vet will likely be able to dispense all 3 after an exam if it is confirmed to a bacterial skin infection. Fungal infections are zoonotic/transmissible to humans and typically present as circular areas of complete hair loss that are often scaly. Good luck!

Thanks for using Petco Pet Education Center, formerly Petcoach! This is possibly due to allergies. It really comes down to figuring out what is causing his allergies so that they can be treated or the specific allergen avoided. A secondary infection is likely and also needs to be addressed.  There are medications such as Apoquel or prednisone which may help with the itch. 

There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. 

Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). 

If not improved in 1-3 months then it is time to move on and check for food allergies by switching to a novel diet (new protein and new carbohydrate). If that does not seem to be the issue then you are left out having to check for environmental allergies which require blood and/or skin tests. 

Allergies can be very frustrating to deal with at first but so rewarding at the end when we are able to treat them effectively!

Thank you for submitting your question regarding Jack. I recommend that he sees a veterinarian. Skin tests will likely need to be performed. Demodex is a mite that lives normally in the hair follicles of dogs. Puppies can experience an overgrowth. This is common in his breed. The veterinarian can diagnose this condition with a procedure known as a skin scrapes. Of course, there can be other conditions affecting his skin. In the meantime, I recommend bathing him with a moisturizing shampoo and conditioner such as an oatmeal or fatty acid based formula to soothe the skin. Place an E-collar on him if he is licking or biting the areas. I hope this information helps!

Hello. They appear to be epidermal collaretts, very typical of some skin infections caused by a staph bacterium. It stands to reason that they are clearing up because Bulya was on antibiotics. You can continue to treat these at home just by using an over the counter anti bacterial shampoo, one with benzoyl peroxide or 2-4% chlorhexidine. These shampoos are available at most large pet retailers or on-line. If you can bathe Bulya twice a week, letting her sit in the suds for 10 minutes before rinsing, all the lesions should clear in 4-6 weeks. If, however, they are not healing or her skin looks any worse, please be sure to see your veterinarian. Thanks for using Petco Pet Education Center, formerly Petcoach.

Thank you for submitting your question regarding Marlo. His belly looks very inflamed and is likely itchy. It is always a good idea to take a new puppy to a veterinarian when you first obtain him. He will need to be examined, started on his vaccinations and deworming. The rash can be addressed as well. It could be a mild allergic reaction, impetigo or even an overgrowth of a mite known as Demodex. The veterinarian will guide you as far as any testing or treatment needed. In the meantime, I recommend bathing him with a moisturizing shampoo and conditioner such as an oatmeal or fatty acid based formula for puppies to soothe the skin. I hope this information helps!

Thank you for submitting your question regarding Chance. I recommend that he sees his veterinarian for skin testing. Skin scrapes are used to look for a mite known as demodex. This is common in his breed. A fungal culture is used to diagnose ringworm. If these tests are negative, then an allergy is more likely. Environmental allergies are common in the summer. In the meantime, you can try bathing him with a moisturizing shampoo and conditioner such as an oatmeal or fatty acid based formula to help soothe the skin. I hope this information helps!
