The MP for Thornbury and Yate, Luke Hall, is calling for more to be done to ban the tethering of horses.
During a session in Parliament on Wednesday Mr Hall suggested that if a 'tether is someone's only method of keeping an animal then they should not have the animal at all'.
He is campaigning for a change in the law that will prevent harm and suffering of horses on roadsides.
In the session, Mr Hall said: "There should be a 24 hour legal limit on how long horses can be tethered for.
"This is important because Defra's code of practice states that long term tethering is inappropriate so this needs to be clarified.
"There also needs to be a complete ban on tethering horses on the roadside in dangerous locations.
"It should be a mandatory duty for local councils to employ an animal welfare officer."
The MP also suggested that the law is not clear enough at present.
"There is currently too much room for interpretation in the legislation so it needs to be clear cut that long term tethering infringes on equine welfare leaving them at risk of long term suffering," he ended.
