Before I start, yes i'm aware I have a long road ahead of me since it was taken from it's litter under the age of 8 weeks and it's a runt, but i'm willing to go through the journey with your guys' help.
I'm currently feeding the 4 week old pup some canned wellness food as it's completely weaned away from formula milk(not my doing entirely). I noticed it would lick the bowl clean. It's ribs aren't showing unless he's stretching and then you'll notice maybe 2-3 ribs at most, but nothing excessive. So my question is, should I let the puppy eat as much as it wants up until 8 weeks or should I keep my current diet for it(pretty much near the recommendation) and just check his weight daily. Also, should I try to merge in as much replacer milk as it will take until it's 8 week, or since it's completely adjusted to the canned food to just leave it is as.
P.S. he currently weighs around 2.4 lbs.
