My 3 1/2 yr old rottie has OCD and just finished his first month dose of Adequan (2 shots/week). He also takes Rimadyl daily (a 1/2 dose for his size), plus CosequenDS, MSM and fish oil supplements. After 3 weeks of Adequan he had a grand mal seizure, and another one a week later. No previous history of seizures. Could the Adequan or combination of meds be the cause?
