My family got a puppy ( I know it's not the smartest thing to do in a house of 4 dogs, wasn't my call ), and the puppy is only about 6 weeks old... any tips on what to feed her? I know regular milk is not so good, and she has teeth, but shes definitely not ready for hard food yet.. any suggestions? p.s. her name is bella and she is a pit bull/german shepard mix
