Help Archie the Great Dane get a Fresh Start

Archie was found outside of an ARC parking lot. Through a series of connections, he has landed at a temporary landing home while we look for a more ideal setup.

You see, Archibald Frederick Van Winston is not just any dog. He is a big, beautiful Great Dane that is severely underweight. His current foster home has two existing medium dogs, and is a foster...apartment. 700 sq feet, not nearly big or quiet enough for Archie! On top of that, he should be eating around 10 cups a day of high-protein big boy food. He was found as a very un-neutered boy, so placing him in a rescue is a bit of a challenge due to this detail.

We are looking for some help to fund this sweet, house-trained, house horse's stay. He is nervous, but adjusting well to a new environment. He just needs a bit of help with massive amounts of food and treats, any vet bills, toys and a collar his size. He is loving, very affectionate, and very respectful of boundaries. Archie just needs your help, a good starting push while we wait for a long-term solution, and any help is much appreciated!!
