There are different anti-histamines in the market. New ones often come in non-drowsy forms but Benadryl, or Diphenhydramine, is the most widely used. This medication is used to treat not only in humans but animals as well. It proved to be very effective and is sometimes used as sedative for anxious dogs.

Just like in humans, Benadryl has many important uses in dogs. Here are the different conditions that can be treated with Benadryl:

  • Itching,
  • Allergies,
  • Anxiety (Separation Anxiety, Firework Anxiety, etc.),
  • Motion sickness,
  • Hyperactivity,
  • Bee stings or insect bites,
  • Allergic reactions to vaccinations,

Aside from the ones mentioned above, Benadryl can also be used to help dogs with mast cell tumors. While Benadryl does not cure these tumors, it can reduce the dangerous effects of having excessive histamine in the body. This medication also helps in controlling the dog’s blood pressure and appetite.

Remember, it is always better to consult your vet to determine the real cause of the signs your Bulldog is showing. What you thought to be an allergic reaction may be something else.


When to take your Bulldog to the veterinarian

Benadryl should only be given to mild and moderate allergies. It is very important to take your Bulldog to the veterinarian if his face is swelling. This is a severe allergic reaction. It can spread to the throat and lungs, leading to allergenic asthma or anaphylaxis.
