'devoted' is the definition.
(I've seen this before)

'loyal pet fed can' is the wordplay.
'loyal pet' becomes 'dog' (I am not sure about the 'loyal' bit.).
'fed' indicates putting letters inside (one word is 'fed' to another).
'can' becomes 'tin' (both are metal containers).
'dog' going around 'tin' is 'DOTING'.

Can you help me to learn more?

(Other definitions for doting that I've seen before include "Excessively fond" , "Devoted" , "Showing excessive love" , "Uncritically fond" , "Overly fond of, say spouse" .)
