In late February, Dallas' broadcast airwaves overflowed with the tragic tale of Lucky the 4-month-old Chihuahua mix who ate a bag of heroin as he sat in the parking lot while his owners ran a pricetag switching scam inside a Carrollton Home Depot. Luckily for Lucky, cops busted his owners and found him in the scammers' truck just after his overdose. Doctors at the North Texas Emergency Vet Clinic saved Lucky's life, and he headed to rehab for a couple of weeks at Carrollton Animal Control Services Center. A Carrollton couple and their 5-year-old granddaughter adopted Lucky on March 8.
