Each year there are awful stories of dogs attacking pets and people, sometimes with fatal consequences.
Tackling this begins with owners and breeders taking full responsibility for their dogs' behaviour and adequately socialising and training them from a young age.
It is also essential that young people understand how to be safe around all pets and learn how to become caring and responsible owners in the future.
In PDSA's view, this should include learning about a pet's five welfare needs at school as well as from other responsible adults around them.
