Inflammation after Neutered

Hi Vets Need help Week ago I had my dog neutered Two days later there was inflammation and had my dog go back to the vet and inject anti inflammatory And my dog was taking dexamethasone and amoxicillin It was getting better but suddenly earlier (9th day) it was super inflamed again I continued the amoxicillin Is this normal? Will this be okay few days later or this is emergency? Any tips for first aid? Thank you

Hello!  This looks like another haematoma, as though bleeding has started again in that area.  I wonder whether your boy's blood is clotting fully for example, or whether he might have banged it.  It is unusual for it to start bleeding again after so long so perhaps your vet ought to see it.  It may be worth calling the emergency team for triage.

It is possible that the photograph shows bruising, and on top of the bruising, secondary effects of licking.  Allowing the vets to triage is still the best next step.  A lot of NSAID drugs cannot be given alongside Dex.  Different sorts of pain relief, and / or some physical means of preventing licking, may be recommended.
