Not sure you spelled that correctly - I found:

Pyoderma literally means “pus in the skin” and can be caused by infectious, inflammatory,
and/or neoplastic etiologies; any condition that results in the accumulation of neutrophilic exudate
can be termed a pyoderma.
Most commonly, however, pyoderma refers to bacterial infections of the skin.

[From the MERCK Vet Manual >>>

“Hot spots” are also known as “acute moist pyoderma”.
What that means is that they are rapidly appearing, oozing, skin infections.

Should be treatable by a good Vet.
