The following is a sentences from a novel.
Let me ask you a quesiton about what are meant by them.

Maybe you could use that dog to get Hammer and Brazil at the same
time. What you wanna bet
Brazil knew Popeye and don't like it none, either, that the dog
disappeared, huh?"
(Isle of Dogs, p131, by P.Cornwell)

Context: This is from the conversation by a street-gang of young boys
who have kidnapped(or dognapped)
Popeye, a dog possessed by Hammer,superintendet of the police. Brazil
is an officer who works for Hammer.
The boss of the members have a strong grudge against Hammer and
Brasil.
The sentences quoted above is being said by a member to the boss.

Question: about meaning of "What you wanna bet
Brazil knew Popeye and don't like it none, either, that the dog
disappeared, huh?"

What I interpreted is as follows:
Do you believe that Brazil knows  Popeye's gone from Hammer's place?

I'm not quite certain of the meaning of "don't like it none, either"
here.
Who don't like it none, either?  or What doesn't he like none,
either?

I'd appreciate it if you give me any hint to get its right meaning.
