i have a jrt x chihuahua pup who is just coming up for 11 weeks, she also is thinning around her neck, and the base of her ears, mine came from a working farm ( both parents are workers) and the breeder ( they arent breedrs as such but thought only way to word them!!) were really knowledgable, and mentioned it may happen as Loki is more chi than jrt, and it is happening just as predicted, they didnt suggest anything to help with the process, and never owning either of the two breeds previously am unsure if i can add anything to her food to help her new coat? she is fed on arden grange puppy and forthglade lifestage puppy meat, both of which look to contain enough oil in the foods to warrant not adding anything else. so i would say good feeding and gentle brushing should help stimulate coat growth ( like hair in humans i suppose!?) so not something i would worry about just yet unless she looks sore or itchy
i hope your puppy is as much fun as mine, loki is a right tinker!
