Hi there and thank you for using Pet Coach to address your concern! It appears as if Gemma may have a skin infection, especially if you are seeing pus in some of the red bumps. I would recommend the following:
1. Douxo PS chlorhexidine combination shampoo and bathe twice weekly until resolved
2. Essential 6 spot on by Dermoscent
3. Malacetic conditioning spray and apply this to the affected area 2-3 times per day

If there is no improvement after using the above or the skin condition becomes much worse, I would have a veterinarian examine this so that the most appropriate treatment can be recommended and further testing be performed if needed. I hope this helps! Please let me know if you have any other questions. I am also available via consultation if needed.
