my 3 yr old has been going through this year round sense 6months old.
hers is so bad the only thing that ever helped her is a prednazone regiment.
be carefull if you go this route! they gain much weight. lately her vet has been trying to have us use antihistamines daily to reduce the amount of prednazone and we are haveing some results but its a strict time table to stick with or she will tear her ears up quickly.
