Which is better for dogs Benadryl or Zyrtec?

Both Benadryl (diphenhydramine) and Zyrtec (cetirizine) can be used to treat Allergies in dogs, but Zyrtec is often preferred due to its longer-lasting effects and fewer sedative side effects. Benadryl may cause drowsiness, while Zyrtec typically has a milder impact on energy levels. However, it's essential to consult your veterinarian before giving either medication to ensure it's safe and appropriate for your dog's specific condition.
