Why does my young dog have dry skin, brittle nails, and coat issues?

I am sorry to hear about Atlanta. I would not say that rashes, hair loss, and brittle nails are normal. As far as whether it could threaten her health it depends on the underlying cause. For example, we can have autoimmune diseases that affect the skin and nails which can lead to more serious illness. I would recommend an examination by a veterinarian who is experienced in dermatology. They may recommend a variety of tests such as skin scrapes to check for mites, cytology and culture to test for bacteria/yeast/fungus, and in some severe cases biopsy of the skin. Treatment options will depend on their findings.

Thank you for posting the pictures. It is possible that it is allergies, but he is a little young for that. I would be suspicious of mites it a skin infection. I would encourage you to have him evaluated by your veterinarian soon. A skin scrape and microscopic exam will likely be recommended to look for mites. Best of luck and I hope he improves soon.

Patchy hair coat can be due to a number of factors, including endocrine disease (such as hypothyroidism), allergies, bacterial or fungal or parasitic infection of the skin. I would recommend an exam at your vet so they can see the hair coat and skin. They may recommend testing such as bloodwork to screen for thyroid disease, or skin cytology to check for infection.

Oh goodness! That does look uncomfortable! It could be just infection, but if it keeps returning then I agree there could likely be an underlying problem such as thyroid disorder, zinc deficiency, pemphigus, or lupus. If I were in charge of his care I would check a thyroid panel and if that came back normal then I would do straight to a skin biopsy. This is the fastest route to a diagnosis. Best of luck and I hope you find an answer and a resolution soon! Thank you for using Pet Coach.

Mites, seborrhea disorders, Thyroid dysfunction, and skin infections are all potential causes of the symptoms you are seeing. A skin scrape can assist in finding the mites. Blood work may be recommended to check his thyroid function. Special shampoo may be recommended based on what is found on examination. Best of luck and I hope Niko improves soon.

I'm so sorry that Duke is doing poorly. Unfortunately skin problems can be very difficult to diagnose and treat because they often look the same on exam and require further testing for an accurate diagnosis and treatment. If Duke has a low thyroid level, then he will need thyroid medication for the rest of his life. I have attached more information on hypothyroidism below. https://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=461 Unfortunately, hair loss can be caused by a huge variety of hormonal and skin problems. Below is a handout that discusses another hormonal disease that can affect the skin called Cushing's disease. https://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=1551 If Duke is itchy, I would also recommend that your veterinarian perform a skin cytology to evaluate for secondary bacterial or yeast infection which is very common with hormonal diseases. https://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=466 I think you will likely need to have your vet recheck Duke's skin, recheck his blood work, and possibly do additional testing to determine the best treatment for Duke. Good luck! I hope that was helpful. Thanks for using PetCoach.

What you're describing does look like dry skin. though some breeds can have naturally coarse/dry skin and fur as well. However, with any skin condition, a complete workup with your vet first is a good idea. They can help rule out any health issues, nutritional problems or skin issues (bacteria, fungus, yeast, etc) that need to be addressed. Making sure to feed a balanced diet or even a sensitive skin food may help in addition to supplements such as fish oils or vitamin E. Not bathing too often and using an aloe/oatmeal shampoo can also help keep the coat frying overdrying and getting flaky.
