I'm not sure if this will help. The thing with puppy kibble is that it is higher in calories than the adult kibble. When you change to adult you will notice that you will be given quite a lot less food. Can I ask how many meals you are giving Ziva? One idea might be to give the adult kibble as one of her meals? I know people who have done this.
We went from Skinners puppy to Wainwrights puppy to Wainwrights adult ( not a success) to James Welbeloved adult to Canagan adult, to Forthglade wet and finally to raw
This has taken 4years to get right!
I think if I was you I would try a different brand of adult food...trouble is that bags a quite big and there could be waste if she spent like a food. But actually you will know very quickly if something doesn't suit her...Don't stick with something on the off chance she will get used to it!
Good luck, Anny and Dude
