Hi can you tell me how to save changes to the RA. I have a small dog that requires nutrients by MW. On the balance screen I can change the values in the table data at the bottom. This successfully changes my parameters but when I add another ingredient or If i save and comeback later the values have changed back to per 1000kcal from MW which are too low for this specific dog.

Hi Laura. ME is not 130xMW. That 130 number is called an activity factor. You can see how we distinguish different activity levels on this web page (see Step 1d - Determining your dog's activity level and energy requirements under the Activity tab):

Hi Laura. Please do not use the tables at the bottom of the Balancer screen. They are for internal use only. Note that you cannot change the RA. Our software does not work with MW, only ME.

Please read this blog here:

Thanks I understand this but for this specific dog I need MW. As stated in the blog to do so.
ME is ok if a dog is on 130xMW although this is the standard for commercial food, most board certified nutritionist recommend 80-100xMW as a standard start.

It did say in the blog that both options would be available in the 365 home edition. will this no longer be the case?
