I was using Eggshell powder and Freeze dried Liver as a topper but after I read your post I decided to try just chicken and CoTW. It worked!! he ate it all. He either changed his mind or he got use to CoTW from me sneaking it in the middle of the chicken.
Yay on 100% raw.
Yes, Call of the Wild has everything in it that Gage needs, therefore by using eggshell powder and freeze dried liver too, he might be getting too much calcium and possibly too much Vit A (probably you're ok on the Vit A.if you're just using the freeze dried liver as a topper). So...what I would do is simply cut back on the amount of each of the other two a little (if you haven't already). But if he likes the taste of eggshell powder and freeze dried liver, then an alternative is to use Alnutrin with Eggshell Powder (which is a supplement), and the freeze dried liver. Just use that instead of Call of the Wild. You would just need to make sure you use enough freeze dried liver with this alternative to equal 5 - 10 % of his overall food intake, rather than just as a topper..
So now everyone is on chicken (meat) and CoTW!! I am so happy!!
