My dog has cancer and is still in pain. Can I increase his meds?

Updated On September 23rd, 2025

Pet's info: Dog | Jack Russell Terrier | Male | neutered | 17 lbs

Last Thursday by taken CT scan, his vet found huge cancer mass L4 area and one of verdebra shown completely black. He is on pain killer since then. I want to bring up dosage since I can see he is still in pain. Until contact his vet on Monday, He is 17 lb dog. 50mg Gabapentune x3/day, Galliprant 10mg x1, Codeine 300 1/4 of 60 mg x3/day. His vet told me “let’s start codeine from 1/4” so I know next move is up the dosage. I can’t reach her till Monday. Thanks for your help

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I am so sorry for De O'Gee's diagnosis. The dose of Codeine he is on is the maximum published dose at 2mg/kg every 8 hours. I can not advise increasing it. You can increase the gabapentin but be aware that will increase sedation. The dose he was started on is below the 10mg/kg every 8 hour starting dose. You can increase the gabapentin to 100mg every 8 hours, but watch for sedation. I wish you the best!
