Support Tango's Surgery, Spare His Life

It is with a very sad heart that I must appeal for help to save our family pet. This is Tango Foots Ferguson. He is a 2-year-old Rottweiler; he's very loving and energetic. He is very affectionate and caring with our grandchildren. Tango has been suffering from a torn ACL which requires a surgery we cannot afford. Please help us save him, our only alternative would be to put him down.
