My name is Jasper!

In desperate need of homing this stray pup found on hwy 377 in August. He's the sweetest boy, and is great with kids and other dogs as well. Tried finding his owners, but no luck. Finally found someone willing to bring him in, but their dog was aggressive toward him, so it unfortunately did not work out. He is not the aggressor, but will defend himself, so he needs to be with friendly pups.
His "fosters" are going to take him to the shelter if I can't find him another place quickly.. I need help. I can't keep him myself, as I have an aggressive pup as well. I also have a cat and he does not do well with cats.
Please consider taking this boy in. It would be such a blessing for him. He just needs a fighting chance. I purchased him a 54"Lx36"Wx46"H escape proof crate that I would gladly donate for his rescue. Anything I can do to help.
He is 80lbs and I would imagine he's somewhere around 3 years old. Still puppy-like but knows basic commands. Goofy and just wants love. Please help him.
