We've been trying to manage them with benadryl, but either we caught it too late, or it's just a bad year. We had to take him into the vet last week. His eyes were getting red and puffy (beyond the normal eye watering red), and his paws were starting to get a bit sketchy also.
He's been on a steriod for the last week and his eyes look TONS better. His paws are back to mostly normal. Only a few more days left and he should be back to normal. The dosage is 2 a day for 4 days, 1 a day for 4 days, 1 every other day until gone (4 more times).
Funny though, with all the steriods, he's not any more buffed out ;)
