Miniature horses are being neglected and abandoned as owners believe their small size means they are easier to care for, animal welfare charities have warned.

Small horse breeds such as Falabella and miniature Shetland are growing in popularity, with buyers hoping their will be enough space for them in a back garden rather than a field.

But rescue centres have warned buyers not to treat the animals like a “cute designer accessory” and look after them as if they were normal size.

Small breed horses can suffer from excessive weight gain, problems with managing sugar levels, and are at increased risk of dental hygiene issues.
