I have been feeding my dog (60 pound Siberian) raw meats since she was a little pup. Feeding your dog anything other than kibble is pretty much always an improvement as dog kibble is notoriously bad for dogs, some of them even causing cancer. I am not an expert, but have done my fare share of research on the topics. Overall, dogs have very different requirements than us humans, as they have a higher acidity to their stomach acids. So, where we cannot eat raw meat, it is perfectly safe for them, but you must be careful while handling it. At the end of the day, the only true difference between raw and cooked meats is that in cooking the meat some of the nutrients are cooked out. Cooked meats are still a world of a difference better than kibble. I'd say good on you for switching things up for your dog, whatever the reasons were, I hope your dog is healthy and happy.
You should see your dogs coat get softer with the higher quality food, and if you are feeding your dog the correct number of calories they will have a healthy physique (ie: when dogs are standing on all 4's they should have an "hourglass figure" between their hind legs, down to their belly, then back up over their ribs towards their front shoulders. You should not be able to see our easily count their ribs, this tells you they are not getting enough food. If their belly is growing, they are eating too much).
Again, I am not a professional, my vet was able to provide me with the correct number of calories for my dog to eat on a daily basis based on our exercise levels and age.
