Long term Permax usage

Makyla Waters <twolegged@...>

Have any of you used Permax longer than a year or even longer? At what
dosage? Have you had to increase the dosage in that time period? There's
so much reference to both permax and cypro becoming useless with time that
I'm wondering what time frame are we usually talking about. I know every
horse is different, but would love to know that some of you are successful
long term users!

Take care, Makyla & 4-legged friends
