A year on and standing

I gave her mum the words that I would not punish the dog again. Then I told my wife I will not be doing that and will carry out more positive reinforcements.

What you did is fine, that's how dogs learn. Why would you let her mom scold about a dog that your WW dumped on you? I'd tell your MIL to stay in her lane, and if she got mouthy more I'd be more frank about what her daughter is doing and ask if she plans on intervening there as well.

I agree with LH in that you need to stop with the R talks, quit talking about her.
