Dear Savvy Senior,

What resources are available to help seniors locate and research Medicare doctors? My husband and I are approaching age 65 and need to find a new internist or primary care doctor who accepts Medicare. Our current doctor is not enrolled with Medicare and will not continue seeing us as Medicare patients.

Dear Savvy Senior,

Is there an easy way to figure out how much savings a person needs to retire? I'm 52 years old -- about 10 years from when I would like to retire -- and I want to see where I stand.

Dear Savvy Senior,

Can assistance dogs help seniors with physical limitations? My mother, who's 60, has progressive multiple sclerosis and I'm wondering if an assistance dog could help make her life a little easier.

Dear Savvy Senior,

I know we will be getting a slight increase in our Social Security checks next year but what about our Medicare costs. What will the Medicare premiums and deductibles cost seniors in 2012?
