I´ve a 3 year old bitch with SM (MRI-scanned). She is having garbaphentin 3 times a day. We found out that it´s important, that she gets it every about 8 hours. Because of the limited possibilities to get the right dose (3* 100 mg/day) - the pills in Denmark is only comming in 600 mg/pill, she is having 1/4 pill 3*/day (= 150 mg *3/day. She is also given a small dose of Furix every morning. She is a happy dog, and seems to have no sideeffects.
