Hi Brenda! Welcome to the community!
There is lots of information to be found that might help Myrt. You might want to start with the threads Questions About Raw Food and Welcome to the Dog Allergies Discussion Group! My 6 year old Corgi boy has had digestive issues in the past. ONP has a product called GI Support, and it has completely cleared up his bowel issues. I also feed a natural and organic diet, starting with Sojos Europa Grain Free premix. The mix is full of wonderful stuff, and is easy to use. Just add in your own protien. I also make sure my dogs get no corn, wheat, or soy products. And, right now, no grain, to see if it will cut down on my Cori girl's itching.
Have fun with the site, and Good Luck!
