Vet bills for Landon

Landon was taken from our back yard, someone busted our gate and we have evidence of him being dragged out of our back yard. (Foot prints, landons foot prints and drag marks) We contacted the police and have an open investigation going now to find the people or person that took our baby. I posted to everywhere i could think of begging for his return and threatening to press charges if he is found being sold or what not.  He was returned this morning with a note stating someones son took him and not to calll the police that they are sorry. Landon has horrible injuries to his backside, legs, and paws The vets said its from being dragged. He also has lacerations in between his toes that go down to the bone and a huge gash that needs surgery.  We are turning everything we have over to the police and they will test the note for finger prints. Hope those mothereffers are caught!!! They will be charged with theft and animal cruelty! We would really appreciate some help with his vet bills. They have really piled on and the extras we had to get him due to him having complications with his first surgery, antibiotics and his pain meds. Anything will help Thank you.
