There has been a big rise in the number of tenants with dogs but these tenants are paying a high price by way of hugely increased deposits. According to one central London agency, the number of applicants with dogs has risen from 2% to 30% in the last ten years. However, 40% of prime central London flats have head leases that do not allow dogs. Homes closest to parks are the most sought after by dog owners and this is reflected in higher rents and large deposits.
