We opened our home to a puppy that was dumped on the side of the road. He was with my FIL for a week and we've had him for about 2 weeks. 2 days ago, he completely stopped eating and drinking and is refusing to get out of bed. He had an appointment for a check up/shots yesterday so I tried not to worry until we got him seen. The vet confirmed that he has hookworms, which explains his lack of appetite. He's been treated with a dewormer but he's not seeming any better yet. He's still very alert, no diarrhea or vomiting but you can already see all his ribs.

My question is, if your dog was already infected with hookworm and was being treated, how long did it take before you saw improvement? I can't seem to find an answer on Google but I want to know if there is hope or if this is the end. It's hard to watch and I want DD to be prepared.
