Caring for a 5 Week Old Puppy?

I have a poodle mix that is turning 4yrs old and I've had him since he was five weeks old as well. What I did since he was so young I made sure to still feed him milk. I found in the pet area at Walmart the little milk carton looks like a little juice box very small. I also bought puppy food and made sure to grind it. The first week I gave him more milk and then slowly and the ground food to the milk. He was so small that I had to put my finger sometimes in his little bowl and then touch his mouth with so he would get the idea.

Also, I went to the vet and payed for a puppy packaged that included all his shots (cheaper as a package). The milk was like $3.50 per carton so I made sure not to be wasteful. I stayed there and fed him to make sure he was eating. Seriously, I think this doggy of mine thinks I'm his mother lol. Good luck. :)
