I accidentally gave my 80 lbs dog 125 mg of Benadryl instead of 75 mg, is that an overdose?

During his evening dose, I accidentally gave my 80-pound dog 125 mg of Benadryl instead of the usual 75 mg. I'm really worried if that's too much for him and what kind of effects it could have. Could you please let me know if this is an overdose and whether I should be doing anything to counteract it?

Answer

It appears that your 80-pound dog received a slightly higher dose of Benadryl than usual. This amount is unlikely to be dangerous, but mild side effects may occur.

  • The typical safe dosage range for dogs is 1 mg per pound of body weight.
  • A 125 mg dose for an 80-pound dog is not significantly higher than the recommended maximum.
  • Monitor your dog for any unusual symptoms.

For an 80-pound dog, the usual Benadryl dose can range up to 80 mg, so while 125 mg is above this range, most dogs tolerate slight overdoses without severe effects. Side effects may include mild sedation, dry mouth, or gastrointestinal upset. Should your dog appear very lethargic, agitated, or exhibit any abnormal behavior, it would be wise to seek veterinary advice.
