My name is Arlo!

Arlo is a sweet, very loving boy. It is very heartbreaking writing this! He has been in my family since he was a baby, but as a baby he was beaten (when potty in the house, bad behavior, etc) and so he has increased anxiety due to this. Vet diagnosed him with separation anxiety, he takes Prozac. He is currently 3 years old, he was born on June 22.
He struggles a lot with time away from his human, so the transition from me to another secure environment may take a while.
He is also reactive to other dogs, and I take a muzzle with me everywhere. HE DOES NOT ACTUALLY MEAN HARM. He is wagging his tail the entire time, and once he is able to calmly say hi to the other dog, he becomes uninterested and immediately wants other human. My assumption is that he was not socialized well with outside dogs (he grew up with other dogs in the home) and so he does not know how to say hi to other dogs.
He jumps a lot when excited (wants to kiss) which I have been working on
