Re-homing our Husky Shepherd Mix

Hi all, I am currently trying to rehome my husky shepherd mix. Originally i took him in from a bad situation (he was found abandonded in a house with nothing but a bag of dog food) and tried to work with him. He can be very reactive with things he doesnt like and tends to nip/bite if he feels uncomfortable or scared. He has PTSD and will also have episodes where nothing will happen and he will be set off. He needs more work than what we can provide at this time and we have a child on the way. This dog is not safe for children which is our main motivator for rehoming him. Besides the negative he is extremely loyal, playful, goofy, and affectionate and absolutly loves long walks, trips to the dog park and destroying toy after toy.
