Hi We are currently treating our budgie "Merry" for diagnosed canker with ronivet-s its been a week now and she seems really good like a new bird but she started having the sames symptons for a brief while does canker take a long time to get over and is it reoccuring, our avian vet sayed it shouldnt come back, she is eating well and drinking the ronivet mixture well????

usually it's a 10 day coarse. The bird will need rechecking after that to see if it was successful.
