Hi When I first got my puppies I was feeding them puppy chow, I wanted to feed them something better, I brought them natural balance lamb meal & brown rice formula grain But that was not doing them good, I switch them to natural balance potato and duck grain free, wasn't good I switch them to iams smart puppy large breed, and the list goes on… The female just had puppies on Thursday morning of February 19 Currently I’m feed them Purina one large breed puppy formula but they still showing signs of not wanted it. I did not want to keep switching them food, yesterday I went to petco to buy them the same puppy food but they run out. So I got them purina one adult dog food with vita gravy with a little bit of the puppy food I had left in the bag this morning the female ate hers but the male didn't eat his till now he still haven’t. I would have take them to the vet but right now things are hard. Is there something I can but to put on their food that would make them eat it can you please help me because the female is kind of skinny her back bones are showing a little bit the male do not want to eat they both only wants to drink water only can you please help me. Think you
