I am a new parent to a 5 week old German Shepherd and I am concerned about his bowel movements. I am not sure if I am feeding him properly. The original owner had said the mother was no longer nursing and the litter had been on canned food since 4 weeks. Is this correct? His bowel movements are very loose and frequent and sometimes it seems as though he strains to try to go. He has a very healthy appetite though but i am not sure of how often and how much I should be feeding him and if I am suppose to be giving him milk. Can someone please help me, I am very worried. I have only had him for 3 days, but My son and I are already very attached. Any information will help. Thanks!
