This list is for your information only. Bedlington-L does not vouch for the companies or any claims that they may make. This is an analysis of copper contents in a number of foods. It was done more than a year ago, and things do change, but BilJac is the same. Frozen BilJac is one of the best dog foods on the market today and if your Bedlington is not affected it is an excellent food.
All dog foods contain copper, but there is a difference.
We used the most popular or the adult maintenance formulas mostly in this paper. Although copper levels vary widely between manufacturers, there is only a small difference in formulas within each company's products. We did not inquire about any prescription products which may be very low in copper. If you convert it to another standard for bulk food, it's slightly more. So, the actual amounts may vary slightly, but you can get an idea where each manufacturer is coming from.
