Congratulations on finding the courage to hit post. Please know that this is a kind, supportive and non-judgemental community and I am confident the trust you have given us will be respected.
I can certainly understand why you feel traumatised. It must have been terrifying to have strangers break into your house, assault your daughter and steal your animals.
The police response doesn't sound right to me either. If I understand correctly, the police have declined to act because the thieves say the puppies belong to them. Is that correct?
Surely that's an issue that requires investigation. And I wouldn't imagine that would make it ok to break into someone's home anyway. Our society would deteriorate rapidly if everyone behaved like that.
You are right to pursue the matter. Perhaps you could also visit the police station and speak with a more senior officer. If that doesn't help you could ask how to lodge a complaint.
I'm wondering if there are security measures you could take to protect your home. New locks? Alarm system? Just thinking that it might bring you some peace of mind.
I'm really sorry for your trauma and am sending nothing but light your way.
Kind thoughts to you
