I posted this yesterday but have not received a response. I really hope you can help as I don't know what to do.
My husband and I just added a 1 1/2 year old (husky mix?) to our family.
He was trained as a racing sled dog so he spent all his time outside chained to his doghouse amid 30 +/- other dogs or in harness. He was too timid to be a good racer so the owners gave him to a rescue. The woman (trained?) him using a prong collar an electric collar for about 1 month. Now I have him and once he learned he didn't have the electric collar he will not come when called. This is a real problem when we turn him and our 1 1/2 year old female alaskan husky out in the dog run. Also when in the house he either hides under the desk or in his kennel, only coming out to let us know he wants outside.

Can you give me any ideas how to proceed with socializing and training him?
PS. He will not accept any treats and he barely tolerates petting while shivering violently.
