  Hi hector10!
  
  Dogs have lots of twin brothers and sisters when they are born, and sometimes there’s not enough food getting to them for them to all become strong, and one or two of them may be in an inconvenient place in their mummy’s tummy and get less food… So when they are born they are weak, so they’re more likely to get ill, and if they are pushed away from getting milk by their stronger brothers.
  
  I think that’s really sad. 🙁
