More than a quarter of tenants would risk their tenancy and deposit to keep pets without their landlord's permission, according to new research.
The information, from a survey conducted by Chestertons, found that tenants find it difficult to find a rented property that will allow a pet, with 77% of private tenants believing having an animal would negatively affect their ability to rent.
Following the survey, the estate agents - which has an office in South Quay - has teamed up with Dogs Trust to promote the charity's Lets With Pets scheme.
Chesterton's head of residential Richard Davies said: "It is concerning to learn that over a quarter of tenants would potentially be willing to breach the terms of their tenancy and risk their deposit in order to keep pets with them.
"However, this research clearly illustrates the true extent of the issue and, while we appreciate that some landlords do not want pets in their properties for a variety of very valid reasons, we are very excited to team up with Dogs Trust and are working closely with them to promote greater transparency and develop more options for tenants who have pets."
The two companies have produced two guides to renting with pets, each containing advice and tips for landlords and tenants to help negotiate a problem-free rental agreement.
Pets at Home marketing director Scott Jefferson, a supporter of Dogs Trust, said: "We're a nation of pet lovers. Currently there are 65million pets in the UK spread across 13million households.
"We are very pleased to see a respected estate agency like Chestertons take an interest in an issue so close to many people's hearts and help to bring responsible, pet owning tenants together with understanding landlords."
