I have a friend who has an 11 year old BC with no teeth and wants to start feeding raw. What can he do to feed her this? Another thing, nobody can answer me for this one and I've been looking, do you need to add in any supplements in for raw?

He can feed ground raw to a toothless dog. Supplements are not necessary on a balanced raw diet.

On a raw diet you normally only feed meat and vegetable/fruit mousse. As dogs don´t really chew their food that should be no real problem.
As the dog will not be able to eat bones, Calcium should be supplemented.

Dennis, a prey model raw diet does not include a veggie slush and thus requires chewing. Dogs on a PMR diet are required chew their food. A BARF diet is more in line with the veggie slush combo you mention but it is not as species appropriate and therefore is not as commonly used as the PMR diet.

FYI, most ground diets include ground bone in them. If that is not the case then calcium supplementation would be required.

You can also find ground raw that has the organs included (5% liver, 5% other secreting organ) as well...
