I just started my dog on phenobarbital today cause she was having seizures , this just started about a month ago when I take her for a walk she would fall to her side and start peddling in the air and it only last a few min and she would come out of it and I would carry her home so the vet put her on low dose of Med .16 milligrams I'm so nervous about the side effects I have been reading online and I'm questioning if I should not put her on this Med and wait to see if she gets worse and then continue it . Has anyone ever started this medicine and stopped it ? I have only given one dose so far so I'm so confused on what to do ??
