Can Benadryl cause hyperactivity in dogs?

I gave my dog a small dose of Benadryl last evening to help with some itching, but instead of calming down, he seemed unusually hyper and restless. I was expecting him to get sleepy, but he was running around more than usual. Could the Benadryl be causing this, or might something else be going on?

Answer

If your dog is hyperactive after taking Benadryl, it could be due to a paradoxical reaction, where some pets experience excitement rather than the expected sedation.

  • Paradoxical excitement can occur with antihistamines like Benadryl.
  • Watch for additional symptoms like a faster heart rate or unusual behavior.
  • Consider environmental factors or stressors that might contribute to hyperactivity.

This matters because, while Benadryl is commonly used to manage mild itching or allergies in dogs, individual reactions can vary. Understanding these reactions helps ensure your pet receives proper care and prevents discomfort or stress for your pet.
