Forgot dog's phenobarbitone: Should I give it or skip the dose?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | spayed | 12 years and 11 months old | 55 lbs

My 13 year, 24.4kg mix breed dog has a brain tumour. She is on 30 mg phenobarbitone twice daily (as well as 500mg levetiracetam 3x daily) to control her seizures as well as a few other medicines. I just fed her her dinner and meds and am having a melt down as i can’t remember whether I gave her the phenobarbitone. Is it better I miss a dose or to give her one but risk double dosing? Thank you for your help.

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. 30mg of phenobarbitone twice a day is not a very high dose for Gum Gum's weight therefore you can give her another tablet now. It will not cause any problems even if it was a double dose for this evening. You should continue with other medications as normal.
