Hopefully the puppy problem will be easier. You can't stop a puppy from doing anything, but you might be able to find something that he likes chewing on more than your cables. Thin rawhide rolls are pretty good (especially if you soak them in hot water first) but IIRC you need to take them away from him before he chews them enough to break off choking-size pieces.
We tried a thin film of hot sauce to discourage chewing but the stains were worse than the chewing. We were smart enough to let the hot sauce dry before putting it near floor/carpet but we forgot that chewing makes the cable wet again.
