I don’t know if this will be helpful because I dealt with this same problem in a different city (Philly) but it plagued me for a long time. What ended up successfully solving the problem was a combo of

Spoke to the neighbors first (they were not nice people and responding by telling me to fuck off, lol). Calling 311 (non emergency line)almost everyday. Recording the noise on my phone when I could. Calling the local council person for my area of the city and annoying tf out of them. Calling animal control repeatedly and speaking to them consistently and politely until they agreed to come out to hear it for themselves. When they came out and saw/heard how bad it was. They issued a citation to the family. I think it was the citation that brought about change.
