All the advices you will find here are from dog owner to dog owner. I am not a veterinarian and I just provide feedback on what we encountered with our three dogs and maybe help you to diagnosis some minor issues.

If you have a doubt about your dog’s health or condition consult your veterinarian!

As a dog owner you probably experienced hot spots on your dog. Some breeds are more subject to it. Examples include the Golden and Labrador Retriever, Collie, German Shepherd, Saint Bernard, Akita, and Newfoundland.
For example Leo and Chester get some but Pumpkin doesn’t.

Hot and humid environments can also make pets more likely to develop hot spots due to trapped heat or humidity at the skin surface where the bacteria reside. The change in the microenvironment encourages bacteria growth.

Also we noticed that with our dogs, 9 out of 10 times they start developing hot spot when they get fleas. Chester is particularly sensitive to flea bites. The rest of the time it’s only Chester struggling with hot spots around spring with all the pollen we get in Houston.

How to treat a hot spot?
If the hot spot just started we usually use Skin Tonic spray from Wondercide. It usually helps to get rid of them. But if after a couple of days you don’t see improvement consult your vet. Keep in mind a hot spot is a symptom so you have to figure out what is causing it to address it. Meanwhile use a spray to relief the itching and scratching.
For Chester we use a onesie to he doesn’t lick himself. He hates cones, the cone of shame haha.

Hope this help!
