Noticed this this morning very fresh so image he has chewed/ scratched it last night. It's up between his back legs. Given it all a good wash and clean and applied cream. I assume it's going to be fungal due to the warm spell we have just had but will have another wash later and see it I can find any more scabbing. I've checked all his legs etc no mud fever and he picked up his feet fine this morning which is usually my first indication that something is wrong.
