Can I give my dog Benadryl?

Often used to treat allergies, motion sickness when traveling, and overall travel anxiety, Benadryl can help dogs get over these issues, but it’s always suggested that you consult with your veterinarian before you do so.

According to the Merck Veterinary Manual, dogs can be given 2-4 mg of Benadryl per kilogram of body weight two to three times per day. Any preexisting conditions or other medications can alter the safe amount your dog should be given.

It takes about 30 minutes for the Benadryl to start to working, so plan ahead if you’re traveling.

Common side effects associated with using Benadryl for dogs include:

  • Sedation
  • Dry mouth
  • Urinary retention
  • Hypersalivation
  • Increased heart rate
  • Rapid breathing

Rare side effects:

  • Diarrhea
  • Vomiting
  • Decreased appetite
  • Increased appetite

While usually safe, it is possible to overdose on Benadryl. Signs of Benadryl overdose, according to the AKC, include:

  • Rapid heartbeat
  • Dilated pupils
  • Agitation
  • Constipation
  • Seizures
