Your mom needs to insist that the police at least take a theft report, she should also contact all the local vets, shelters, etc, in case they try and dump the dog. She should then speak with an attorney regarding her next steps - hopefully, a letter from a lawyer threatening legal action will be enough to get the dog back. Gook luck.
If we do not have a signed fee agreement I am not your attorney and this is not legal advice.
That's awful! I agree with counsel. The police should at least make a report. I hope your mom has pictures of the dog with you guys. Talk to a local lawyer about sending her a letter. Otherwise she can sue them in small claims court. Good luck
It is very difficult to get the police to become involved in pet theft matters, but your case is clear. I would approach the police again to file a report, but I wouldn't let that delay you in taking legal action. You need to get an attorney immediately. That attorney should send a demand letter demanding the return of the dog in a short period of time and threaten to file suit if he is not returned. I agree that all local shelters and veterinarians should be contacted with photos and your contact information . Keep in touch with them, as well. I understand that it is possible to post an amber alert type notice on some pet lost websites. You may want to look into that as well.
This is not to be construed as legal advice. I do not have an attorney client relationship with you.
