Just make sure your dog will eat rats. We feed raw and she will NOT eat the rats, no matter what I do to them. They are frozen/thawed.
We have 14 snakes, I have 1.4 in 5 bins and the 6th bin is grow out. I spend $30 a month for bedding/food. I get Mazuri 6F in the big bag. I have extras to sell. Sometimes my largest females get fed multiples simply because I don't have the room to raise up to medium rats, but they are probably large smalls. This is just when building back up from laying. Otherwise, they only need smalls as larger prey is not fully used in digestion and pooped out.
Hope this helped.
