I just had our first raw litter and they are 5 months now. We were careful to stop bone in mom's diet the last two weeks and increase heart and beef. She was 7 and did great. She looks better now than she did when she was 3. The pups nirsed and we fed mom in their pen. They started to get interested in her food about 3 1/2 weeks. At that time I ground chicken with some organ and goats milk. They started one meal a day and by 5 weeks they were eating three meals per day. At 5 1/2 weeks we changed from ground to chicken wings, duck necks, chicken necks, and then to chicken legs, chicken thighs and cornish game hens. At about 8 weeks we started adding beef, then 2 weeks later organ. They look fantastic. The pups I kept have incredible muscle tone, glowing coat and lovely calm demeanor I believe is at least partly due to being able to really chew and enjoy their food. They really get a work out. If you don't have a grinder ground chicken or turkey can be purchased.
