Beagle was rescued from a laboratory:

 Reggie (a Beagle) was rescued from a laboratory where dogs are used for medical testing. From a silent, trembling dog who had spent years in a lab, 

Reggie burst into tears of joy when he was finally able to bark freely for the first time — a bark filled with the happiness of freedom and a new life 💗✨
