Dog harness, bed, and crate (Antioch)

Hello…Looking for a dog harness that would fit a 45# (and growing) female German Shepard puppy, a large crate, and a dog bed. She’s a rescue that we’ve fostered for 3 weeks now. She was underweight, flea infested, skittish, and scared when we got her. She’s doing better each day. Any toys, treats, supplies, or food would also help and be very much appreciated! Thank you in advance!
