Want a rock-solid relationship with your dog? Hypnotise him and you’ll soon have him fetching your slippers and bringing you the paper. Just kidding. The Purina PetLife Hypno Ball Tug Small isn’t actually for hypnotising your dog – but play is the most powerful way of developing a bond between owner and pet, and this toy is just the thing for playful interaction. The bright colours will help hold your dog’s attention, and the soft rubber ball is suitable for sensitive teeth and gums.
