Like the dog annoyed at being carried about? (2,2,4)

I believe the answer is:

up in arms

I'm a little stuck... Click here to teach me more about this clue!

'like the dog annoyed' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'at being carried about?' is the wordplay.
I cannot quite see how this works, but
'at' could be 'in' (synonymous in some cases - eg at school, in school) and 'in' is found within the answer.
'being' could be 'ms' (Ms. is an example) and 'ms' is found in the answer.
'about?' could be 'a' (abbreviation in Chambers) and 'a' is found in the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for up in arms that I've seen before include "Protesting vigorously - got guns?" , "Protesting vigorously, in militant mood" , "openly rebellious" , "Involved in protest" , "being angry" .)
