He was on Nutro dry Chicken [Regular] until seizures started DEC '08. I've since tried: Blue Buffalo, Canidae, Innova Red Meat dry, & EVO 95% red meat canned mixed w/ dry. His seizures seem to happen less often since Vet started Pheno & potassium Bromide (but still cluster of 4 every 6 weeks). The thing that's been troubling is his gas has always been terrible. I've tried every digestive powder I know of. I've also been very careful weening btwn brands (and keeping on for at least 3 mos each). He's pure bred, very tall, & 105lbs of pure muscle. Out of control hyper after each seizure.?.?
