I'm a little confused by the structure of the sentence. How to understand “suspicious treats through the fence”?

Question

I met a sentence on Twitter:

Russia is like an oddly solicitous neighbor who you eventually find out is stealing your mail and feeding your dog suspicious treats through the fence.

As an English learner, I'm a little confused by the structure of the sentence. How to understand "suspicious treats through the fence"?

My analysis is:

Russia [subject]

is [link-verb]

like an oddly solicitous neighbor [predicative]

who you eventually find out [attributive clause modifying "neighbor"]

is stealing your mail and feeding your dog [object clause]

suspicious treats through the fence. [???]

Answer 1

This sentence has a compound predicates:

stealing your mail

AND

feeding your dog (indirect object) suspicious treats (direct object) through the fence (prepositional phrase)
