Having worked in medicine for 150 years - I know that some doctors tell their concerned patients that "Some people go to the bathroom three times a day and others go three times a week - and either is perfectly normal --for that person." I'm sure this might apply to dogs also. At least, there should certainly be some variation in how often or when these little guys go to the bathroom.
I wouldn't worry about it. My one dog usually goes once a day - and it seems like my younger pup goes several times a day. Whatever!!! My dogs eat well (their stools appear normal) and they are happy, healthy, and playful.
