sometimes this happens. i would not think the food would make any difference in how the eggs attach to the uterus. it appears to me it is the timing. i would have an ovualtion test next time and maybe you will see a difference. dogs don't always produce the same amount of litters each time as some people might think.
i have always used science diet small bites.
