Some articles I have found say it's 3-5 times a day, some say 2-3 times a day with no more than 8-12 hours between times when dog gets out.
My mother's dog (English Springer Spaniel) is used to being taken out 2 times a day. 7-8 in the morning and ~11 in the evening. He only poops in the morning. He seems to be used to this schedule, he does not seem too needy in morning and evening.
I guess my question is, is twice a day not enough and is this hurting the dog in the long run?
Or should I convince my mother that 3 times are needed?
