Boring type carrying articles for old animal minder (8)
I believe the answer is:
neatherd
'animal minder' is the definition.
(someone who looks after cows)
'boring type carrying articles' is the wordplay.
'boring type' becomes 'nerd' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'carrying' indicates putting letters inside.
'articles' becomes 'a the' ('a' and 'the', indefinite and definite articles).
'nerd' going around 'athe' is 'NEATHERD'.
'for old' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Another definition for neatherd that I've seen is " Drover".)
