She's doing quite well. She takes 100mg once a day. I just toss it in with her kibble and she wolfs it down. Her bowl looks like a pharmacy!
It took a week to see any change. It hasn't been a miracle cure, but there has definately been improvement. She is steadier on her feet and seems more aware of where her back paws are most of the time. She still stumbles occasionally and sometimes drags one of her back legs, but she hasn't fallen right over in at least a week. I haven't seen any negative side effects--no GI upset, ect.
Pirate will never fool anyone into thinking she's a youngster again, but the meds do seem to be keeping her from getting any worse. I hope you find something that will help Louie too.
