What causes a white flaky patch on my Min Pin's hind quarter?

It's tough to say exactly what's causing Pablo's patch of hair loss from a picture alone. I agree that I don't see any redness, scaling or signs of inflammation in the picture. Some possible causes can include scar tissue from an injury or burn, infectious conditions like mange or ringworm, a sebaceous (oil gland) cyst or histiocytoma. Pablo should be examined by his vet so that diagnostic testing can be performed. It's likely that your vet will need to take samples from this area to be evaluated under the microscope. Once the cause of this issue is diagnosed, then your vet will be able to determine the best course of treatment. This is certainly not an emergency, so if many of your local vets are currently closed or have less availability, it's not a big deal if you need to wait a few extra weeks. I hope this helps and that all goes well for Pablo!

Thanks for using Petco Pet Education Center, formerly Petcoach! I think continuing the use of a medicated shampoo would be good as he likely has secondary infections. I think this could be due to allergies and it would be crucial to identify the allergic component to try to see if he can improve. It really comes down to figuring out what is causing his allergies so that they can be treated or the specific allergen avoided. 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!

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. This could even be a granuloma from her licking at it. There is no way of knowing what it is just based on its appearance. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have her evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!

Any time we have areas of hair loss it is recommended that your dog be examined by a vet. From one photo it looks like we could either have dandruff or epidermal collarettes which are a sign of bacterial infecition of the skin. The pinpoint white areas could be pustules (from bacteria) or calcinosis cutis which can be see with some endocrine diseases. The vet will examine Max and may recommend some testing to check for bacteria or parasites or endocrine diseases. Treatment will depend on their findings.

Hmmm, it sure does make him look cute, though! This is a very interesting pattern of hair growth. It is quite possible it is just how his hair grows! Possible causes for this (although not very common in puppies) include hypothyroidism, endocrine or hormonal disorders, or color dilution alopecia since it appears to be no hair growth in the blue areas. I recommend that your vet test his different hormone and endocrine levels to see if there is a treatable cause. If it is alopecia, you can try supplements (discuss an appropriate dose of melatonin with your vet) but there is no cure. For the sores and bumps, common causes include fleas, mange, infections (bacterial or yeast), ringworm, allergies, among others. You can try a medicated shampoo like Dechra MalAcetic Ultra Shampoo as well as a good flea preventative like Seresto Collars or a prescription oral feal preventative. https://vcahospitals.com/know-your-pet/color-dilution-alopecia-in-dogs

I would get this checked by your vet as soon as possible. It could be a number of things, from fungal or bacterial infections, to mange. Identifying it quickly can save a lot of time and trouble as some of these conditions are a challenge to clear up. Your vet will do an exam, pluck some hairs and possibly do a skin scrape, which involves scraping a dulled scalpel blade on the skin to remove hair and a little skin to examine under the microscope. Based on these tests, your vet will be better able to tell you what is going on with your puppy's skin and how to treat it.
