Hi Possum,
I’m so sorry, I’ve been meaning to reply all week. Ernie is doing really well thank you.
Thankfully, the vet wasn’t too concerned and was confident that it’s not CLA. She removed the remaining pus and advised spraying with iodine morning and night to prevent infection, and also re-applying Spot On to help protect from flies. It’s healing really nicely and there’s been no further swelling or pus. It’s turned quite hot and sunny here today and as the wound is healing well, the vet was also happy for us to now apply some Battles yellow fly cream for some extra protection.
Thank you again to everyone for your help, I really am so grateful for the amazing advice and support.
