Thank you very much for the feedback about the fox. However, upon doing several tests I was able to "give out" instructions to my fox after taming it. I used other items except the taming item and so far it worked out fine. The only issue I see is if you right click the fox while it is still "in love" mode (hearts flying about) you would not be able to see the current command it has, hence it would seem that it does nothing. But I do have to check that renaming option you mentioned since it did cause a crash.
The GitHub repo for PZ 1.7.10 is very much open for issues so you can either post your issues here or in the repo.
