Hi! Thanks for entrusting us with Chyna's care. Loose stools is not a typical sign of an allergic reaction though anything is possible when that occurs. Also, it could have been secondary to the Benadryl though not typical or just dietary indiscretion from eating something else. Just continue to keep an eye on her for now. If it worsens or just does not improve, have her examined by your veterinarian. Good luck!
