My dog's on methocarbamol. Can I stop it due to peeing & panting?

Updated on September 23rd, 2025

Pet's info: Dog | Newfoundland | Male | neutered | 107 lbs

My elderly dog was prescribed & has been on methocarbamol for 3 days and I want to stop it . He started urinating in house and breathing heavy. Can I stop it cold turkey and how long will it take to get out of his system?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach!

Methocarbamol is Robaxin which is a muscle relaxant. It can cause sedation or grogginess. It doesn't need to be weaned and can be stopped abruptly. I would say it should be out of his system by 12 hours but some animals are more sensitive than others. I would recommend reaching out to your Vet about this side effect. If his breathing is concerning he should be seen as trouble breathing can be life threatening. If he is on other medications like steroids (medrol or prednisone) it is much more common to have these medications cause urination in the house and panting.

I wish you and Porter the best!
