Mixing wet and dry food is great. I can’t suggest foods for you because I don’t know what has small kibble sizes, but someone else will see this soon and have ideas.
About the rawhides, does the package say where they were made or if they are natural hides? Throw out anything made in China because you never know what chemicals may be in it. If they are not natural rawhides, then they were treated with something to bleach them and it is unlikely to be something good. However as long as you only give them very occassionally they are unlikely to do damage, but it is something that I would only use rarely, just to be safe.
Congratulations on your new family member!!
