I was having the same problem with my baby - I was feeding her nutro but after all I read on that food I changed her food to Orijen it is great I was feeding her 3 times a day (Nutro) it was a total nightmare! anyway her vet told me to feed her 3 times a day but it was total nightmare and she wouldn't eat either, anyway i changed it to twice a day and of course she gets her treats when i train her
so now she goes poop at scheduled times after her meals and in the morning before she eats breakfast so everything works out good now she's now four and ahalf months but she's healthy and happy
