My dog has a grey rash, hair loss, and elephant skin. Is it serious?

Poor Oakley! He needs to see the veterinarian. The odor is likely due to secondary bacterial or yeast infection. The primary problem is likely skin mites or an allergy but thyroid disease is possible. He needs medications and likely a medicated shampoo. You also need to know the underlying cause or this is not likely to go away. Best of luck and please feel free to post any additional questions.

Thank you for providing pictures of Achilles's belly! Yes, I would take him into the vet. It certainly isn't normal to have a rash on the belly, and it could be caused by a contact allergy, ringworm, or a skin infection. The vet can diagnose what is causing the rash so it can be treated. I would take him into the vet in the morning.

The area on the side of his face looks like it has a bacterial infection causing the raised bumps. Your puppy should see your veterinarian to determine if this is the case. They may also want to do a skin scraping to look for any skin mites that may have started the problem. It looks like your pup will need prescription antibiotics to resolve this problem.

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!

It looks like Lilly may have a skin infection. When yeast or bacteria overgrow on the skin it causes inflammation, and when that has been going on for awhile the pigment of the skin will turn darker. Yellow flakey/waxy skin is also a sign of a skin infection. I would suggest that the owners take Lilly in to see their vet. They will be able to discuss special shampoos and prescribe any necessary antibiotics. They will also evaluate Lilly for any underlying health issues making her more prone to skin infections.

Poor Revi! I would take her into a vet first thing in the morning. If she has awful yeast infections, she will need anti-fungal medications to treat them. She could also have an underlying bacterial infection, and might need antibiotics to treat that. I would also recommend stopping the raw meat diet. Oftentimes, these homemade diets are not properly balanced with all the nutrients and vitamins she needs to be healthy. In addition, these raw diets pose a health risk to both you and Revi in that both of you could get infected with salmonella or Ecoli. I would feed her a high quality dry dog food, such as Royal Canin or Hills Science diet.

Poor Star! I can see that she has a large amount of redness and hair loss on her shoulder and thigh in the photo. Yeast infections, bacterial infections, mange, skin allergies, and even certain hormonal imbalances can cause these signs. Because of how severely affected the area seems to be, I definitely recommend having Star seen by a vet, as she likely requires prescription medications. I hope all is well!
