1st i would like to congratulate you on taking the pup on and giving it a good home
2nd ive fed my dogs milk ever since they could eat all the waiste from the cows after milkin goes to them and ive never seen a problem but thats just mine,
and 3rd as the man said good quality chicken and beef will see it grow quick
but they are what they eat,and the taste of the pork reflects on what you feed them,so swill and shit is out,but pigs like foraging and if you have the land grass and roots subsidise a lot,
