My dog's had these spots in her skin for some time. I'm including photos of the lesions. They're very itchy; she's always scratching herself. They also smell.
What can it be and what medication can I buy? I prefer medication that can be taken orally because it's very hard for my parents to put ointments, creams, etc. on her.
I bathe her biweekly with an oatmeal shampoo for dogs.
We live in a very hot environment where the temp's been over 90 °F (32 °C) the last few weeks. She sleeps most of the day.
I don't believe she's in pain; she wags her tail, eats well, runs and walks normally, etc.
Any help would be greatly appreciated.
