PDSA is running a campaign to encourage pet owners to reconsider the diet they feed their pets.
The PDSA charity says a large number of pet owners in Wales and across the UK aren't feeding their animals the right diet.
The organisation warns that a poor diet combined with a lack of exercise could lead to reduced life expectancy in a pet.
