James Wellbeloved Dog Food

How much do I feed my dog?
I have a 3 year old male neutered cocker spaniel (unworking), which we feed James Wellbeloved adult dog kibble.
I am an animal management student and know how to work out how many calories my dog should be having per day (784)
How can I find out how many calories are in his food so I know how much to feed him? I can’t find this information anywhere.
If the calorie counts are not listed on the bag nor on the manufacturer’s website, then you have to call or email the manufacturer to get them.
Here’s the contact information from their website: http://www.wellbeloved.com/about_us/contact_us.aspx
