This rash could be caused by an allergic reaction, fleas, mites, or a skin infection. I would have your cousin take Mak into the vet tomorrow. The vet can diagnose what is causing the rash, and can treat him. I hope this helps!

Hello and thanks for using Petco Pet Education Center, formerly Petcoach! To me that looks like it could be a rash related to a mite (like demodex) or a bacterial infection. In that area it could also be a result of a flea allergy or even a topical reaction if you have applied anything to that area recently. It would be a good idea to take Boyshow to your veterinarian so that a skin scrape and cytology sample can be obtained. These diagnostics will show if mites or bacteria are causing the problem and an appropriate medication (like antibiotics) can be dispensed.

My dog has a polka dot rash on belly. Should I take him to the vet?

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.

Why does my dog have a bad rash and what's the best next step?

Oh that is bad! Poor Blue. I'd take her into a vet today. She could have mange, a bacterial skin infection, allergies, or fungal skin infection causing this rash. The cause needs to be diagnosed in order for the correct treatment to be prescribed. I hope this helps!

My dog has a skin rash. What are the causes and how can I treat it?

It looks like he has a skin infection. You could bathe him with an antibacterial dog shampoo but he will likely need an oral antibiotic to treat the infection. Call your vet and schedule an appointment for treatment.

My dog has a rash that's getting worse. Should I take him to the vet?

Hi and thanks for your post. It is hard to say exactly what the cause of Blitz's rash may be due to without examining Buster first, but I can offer some possibilities and next steps. Some possibilities may include a fungal infection, bacterial infection, mites, a food or environmental allergy. Your veterinarian can diagnose these potential conditions with a fungal culture, skin scraping, and/or an allergy screening. I would recommend Blitz visit his vet soon to get a definitive diagnosis so the most appropriate treatment can be prescribed. Best to you and thank you for using Petco Pet Education Center, formerly Petcoach!

Why does my dog have a rash with red dots, dry skin, and shedding?

You will need to take your dog to a veterinarian for a skin exam. Your dog could be suffering from an allergy, mites, fleas, a bacterial or fungal infection. Each of these requires a different treatment, so it is important to find out what is causing the the rash. Your vet will do a thorough exam and maybe a skin scrape. He will then discuss the options with you and then prescribe medications, possibly give an injection to stop the itching, if your dog is itching.

My dog has an itchy rash on her backside. What's the best solution?

The only way to get rid of it is to know what is causing it. This itching could be caused by fleas, mites, allergies, or ringworm. I'd take Ellie into the vet first thing in the morning. The vet can diagnose what is causing this rash, and can prescribe medication to treat it. Best of luck.

My dog feels hot and has a rash. When should I take her to the vet?

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. If you think Dakota is warmer than usual and has developed a rash, she may be having an allergic reaction to something. I would recommend having a veterinarian examine her so that the most appropriate diagnostic treatment recommendations can be made. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
