The intentions of the TV advert are to specifically target the audience's deepest and most heart-felt feelings towards animals.
By representing individual situations humans and animals share together, the advert illustrates how animals are ALWAYS with you through both positive and negative experiences. It also conveys how most people consider animals to be more than just pets, but life long friends.
The use of emotive images and the personification of animals encourages the audience to believe that animals and humans share a personal relationship.
The advert then goes on to conclude that by donating to the PDSA, you are effectively 'giving something back' to the animals.
