For dogs that tend towards aggression, lowering the protein can sometimes help. I have a Beagle pup who gets “the crazies”, and will sometimes get so worked up that it turns into aggression :/ In this instance, switching him from puppy food to adult with 23% protein drastically reduced the hyperactivity. Sometimes dogs can get a reaction from certain types of protein, so if he’s been on chicken, try beef, lamb, fish, etc.
Ditto to anon101’s raw food warning. Lost count of the times over the years raw sent my dogs to the Vet (we also had a bowel obstruction once), and my second Beagle, who was a sweet, friendly little pupper turned into a food obsessed, aggressive, stand-offish jerk on raw. Completely changed his personality. That, and it most likely was the cause of his seizures.
