Hi I wish I knew the answers to your questions but I really don't. I tried looking online for a high fiber homemade recipe for your pet but I couldn't really find one. Instead I got websites that suggest raw food diets (which I am not familiar with). I just started my dog on a homemade diet of chicken, rice, carrots, and celery. I posted the recipes on here if you were interested. But the websites online really recommend raw heart, and liver. But I don't know if I feel comfortable with that, to be honest.

If I were you, I would contact the vet and ask them your questions since they really are the most informed about this stuff. When I asked my vet, they gave me handouts of recipes. Sorry I couldn't be more help. Good luck!
