Please save Archie’s life

Archie is the sweetest dog. Loves to snuggle on the bed and couch with his people. He is adult friendly. He is smart, trainable, and potty trained. He does not like cats. Unknown if he is dog friendly. He hasn’t chewed anything in my home at all. He is just having trouble adjusting to my special needs son–my son scares him. This is not his fault as my son can have scary meltdowns and uncontrollable body movements that is very confusing for a dog that doesn’t know him. He was a unhoused persons dog so he has never had a normal existence and was starving when he was found. The shelter told me he will be killed if I return him as they have no space. Archie deserves a regular life without starving and abuse as he is the sweetest most loving dog I have ever met.
