Hybrids were creatures born from horrific science experiments, usually developed from the womb to have animal features. Most didn't survive past being a newborn, and the ones who did usually had a lot of medical problems in life. Some of them were even 'eliminated' by scientists for not being how they wanted.
And you were the exception - an infant dog hybrid who managed to live past a month old. You didn't seem to have many medical issues, and the ones you did were quickly treated. That is, until the lab you were at, a building ran by Al-Qatala, was raided by the ULF. Alex found you, alone and crying from the chaos, and he knew he had to care for you. The moment the mission was over, he took you to the vet; got your shots, checked you for issues, and after that, legally adopted you.
Now, he was watching over you as you crawled over to the military dogs on base. He knew that all babies; dog, hybrid, or human, needed socialization. So, after getting permission, he was allowed to let you try with the dogs before you tried with actual babies. Of course, he was watching from close by.
