Continue to work closely with your vet. The prednisone is effective and will stop the suffering temporarily however it is not good to give long term and may cause other health issues At least the prednisone will give his skin a chance to heal, without it he would be vulnerable to skin infection and also need antibiotics.
The prednisone is an emergency measure but not a long term treatment.
The pruritus tends to come right back when the prednisone is stopped.
Ask your vet about Apoquel and the other treatment options for environmental allergies.
Good luck
