How do you deal with/block out barking dog noise in a block of flats?

Genuine question.

My downstairs neighbour has a yapping dog that frequently enjoys a barkathon whenever the buzzer goes, the door entry gets slammed, anyone walks up or down the stairs, etc. It’s insufferable at times, especially when trying to watch TV or something. Even getting to sleep because they go in and out overnight at stupid times.

Obviously tried talking to the neighbour about it (and also her excessively loud voice when talking on the phone to the point I can transcribe each word of her side.of the conversation) but it’s done nothing so I’m pending a response from the council noise team but in the meanwhile anyone got practical tips or suggestions?

TIA.
