Anything I can do for my puppys throat?

I've had Chip (8 weeks) since Friday. He barks when alone then settles downs after 5-10 mins (was more like 2 hours the first day) now. From the first two days he would bark nonstop when alone til he fell asleep. At this point the barking is slowing, but his bark/yelp is so hoarse/quiet due to his throat being sore from barking so much. Is there anything I can do for him or just let it be?
