hi im also very new to this, I have a 7mth old Staffie called Sapphire, but has the need to eat her own poo!!! She has been doing this since we had her which is 4mths now. We also have another dog a Jack Russell called Gizmo who is 1yr old. Im finding it hard as she is still not house trained I wake up to 3 poos and as many wees, but a mark where some of the poo was!!! we take her out 4-5 times a day. My vet has told me it is a behaveral problem (sorry cant spell lol) and isnt lacking in any vitamins. Other than that she is the best anyone could ask for she gets on very well with my children 12,10 and 4.
