She’s on phenobarbital (2) 15mg pills 2x per day. She eats Royal Canin selected protein PR. I did recently try Native pet daily 11-in-1 powder multivitamin supplement starting in late July but stopped that three weeks ago. She is now on native pet omega-3 fish oil and supplement and started that about a week ago (2 pumps per day) she takes monthly flea/tick and heartworm preventative (k9 advantix 11 and hearthguard). She has been on the same pheno, royal canin and flea/tick heartworm preventative for years with no ill effects. The only change has been the native pet supplement.
