Doctor vents one lung - making news programme's introduction showing individuals that require a helping hand? (5,7)

'doctor vents one lung making news programme's introduction' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'individuals that require a helping hand?' is the wordplay.
I cannot quite see how this works, but
'individuals' could be 'pets' (pet is a kind of individual) and 'pets' is found within the answer.
'hand?' could be 'glove' and 'glove' is found in the answer.
The remaining letters 'pup' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

'showing' acts as a link.

Can you help me to learn more?
