Does this sound about right?

Hi, this may be a long post about raw feeding but here goes:

after the comments on another site about the pre ground mince I was getting from the butchers not being the best plus lack of avalability I have started to look into raw suppliers, does this sound about right with my calculation for 1 cocker (15kg) 2 huskys (17kg each) feeding 2.5%:

Mince chicken- 60lb should last about a month,
2 beef tripe-approx 20 kg should last 3 weeks
4kg Liver, 4kg kidney, 4kg heart should last about 4 months
15 kg bone should last about 4months.

Am I missing anything vital at the moment i have used the 80:10:10 ratio

Also ordering hooves stuffed with mince as a treat rather a meal

Thanks

What is too much for one dog may not be enough for another, so you'll have to keep your eyes on their waistlines and also their poos, which should be small, brown and firm, sloppy cow pats are a sign of overfeeding, white crumbly poos are a sign of too much bone.

How wonderfully put TW

Thank you
I know it's a learning curve but wanted to make sure I wasn't missing out a huge chunk of something before I placed the order as they only deliver monthly in this area, the two adults have had offal in the past with no problems as a one off treat, even just the last week (on mince) I have noticed the improvement especially on the poo picking front hehe
