My dog has an itchy red lumpy rash and feels hot. What's happening?

Yes, it looks like an allergic reaction. I suggest you get him to your vet for an exam. In the meantime you can give him some antihistamines to see if that will reduce his symptoms. I have no idea what antihistamines you have available to you in Australia so I will refer you to this link of common ones used. ( https://www.albertnorthvetclinic.ca/antihistamine-chart.pml )

Poor Teddy! It sounds like he is suffering from some severe allergies that is causing this persisting rash. I would take him into the vet for an exam. It sounds like he could use a strong medication to stop the rash, such as a steroid. I would take Teddy into the vet today or tomorrow during normal business hours.

Poor Spud looks like he may be having an allergic reaction to something, and also likely has a secondary bacterial infection going on. He needs to be seen by your vet to get a better idea what is causing the skin issues. He likely needs to be on anti-inflammatory medication like Apoquel or Prednisone, and an antibiotic. This will make him feel better and heal the skin issues. You can apply an epsom salt/warm water compress to the rash areas on the neck, but he really needs to see a veterinarian for proper treatment and medications.

Yes, I see what you mean about Winston's skin. The single mark could be from a tick or a black fly bite. The rash is also concerning. I do think he needs to see a vet for these problems, and I would take him into one in the morning.

Thank you for submitting your question regarding Loki. I am glad that he is seeing his veterinarian. He may have a bacterial skin infection. This can happen for a variety of reasons, but allergies are a common cause. Has he been licking the area? This can make it worse. I recommend bathing him with a moisturizing shampoo and conditioner such as an oatmeal or fatty acid based formula to help soothe his skin. Place an E-collar on him if he is licking. I hope this information helps!

Poor guy. He is likely having an allergic reaction to something he was exposed to outside. You can give him an antihistamine to see if this improves things. As long as his breathing is ok and there is no swelling around the neck, he is likely to be fine after 12 hrs or so as the reaction subsides. You can also try bathing him in an oatmeal or hypoallergenic shampoo to help calm down the skin. If the skin reaction does not improve or worsens by tomorrow then have your vet take a look at him and they can administer stronger medications to subside the skin reaction. It will take a bit of investigating on your part to figure out what he could have been exposed to to cause him to break out into hives.

I'm sorry Fox isn't doing well! It could be that he is experiencing an allergic reaction, causing the pinkish red color of his skin, the pimple things, and making the skin feel hotter than normal. He could also have an bacterial infection causing his symptoms. Without seeing him in person, I couldn't say for certain what is causing his symptoms, but it sounds like from your description that he needs to see a vet. A vet can diagnose what is causing these symptoms so he can be treated. If you can, I would take him into a vet today, even if that means going to an ER vet or finding a vet on call to see him. I hope this helps, and good luck!
