My name is Optimus!

I am looking for a loving home for this foster baby Optimus. I agreed to watch him for a family members friend when they disclosed that their home situation was not good and that Optimus was in danger. I have had him for several months now and the owner has become unresponsive.
I am not able to permanently keep him, my cat's are always stressed and Optimus needs a lot of love and attention. He is kennel trained, has done well around kids and other dogs. Unfortunately I am unsure about vaccinations, since his former owner no longer responds to my messages. He is about three years old, and the previous owner states he is a husky mix. If you are interested please let me know. I will be sending him to his new home with his kennel and dog food to help with the transition. He really is a sweet boy, I just am not able to keep him without jeopardizing the health of my other pets. I have reached out to a couple of rescues but have not heard back and this has become a time sensitive matter.
