Can I give Benadryl to my Frenchie? Yes, you can give Benadryl to your French Bulldog. For several ailments, vets recommend Benadryl for most dogs. These include motion sickness, autoimmune and allergic reactions from bug bites, and seasonal allergies, which can all be helped with medication like Benadryl.

Chemically, the active component in Benadryl, diphenhydramine, is very similar to the active element for Dramamine. Dramamine is an over-the-counter travel sickness medication that a veterinarian can also prescribe for dogs.

Because of the similarities between the two medications, Benadryl can be useful in helping your Frenchie cope with nausea caused by vehicle motion.

However, they are often combined with decongestants, which can cause serious health risks to your dog. Here are some alternatives to giving your French Bulldog Benadryl. Before giving it to your pup, any new medication should always be discussed with your veterinarian. 

When acute allergic reactions, it is best to use faster-acting methods to relieve itchings, such as cortisone creams or injections. These treatments are effective within minutes. Nevertheless, cortisone treatments should only be used for a short period. Extensive use may cause discomfort.
