Lost Dachshund/Sausage dog

Brakkenjan our 14 year old, sterilised, male dachshund went missing in the last 2 days from the corner of 16th Avenue and Beyers Street in Rietfontein. He is not wearing his collar. He means the world to us. He is terrified of rain, thunder and fireworks. Please help us find him ASAP.
