I have a 5.5 month old german short haired pointer who does this also, but he isn't so picky lol. he eats his own poop (frozen, and fresh), cat poop, and rabbit poop from out in the yard. He will eat any poop he can find. it is very stressful for me as i have to keep baby gates up in the house so he wont go excavating thru the litter box. he comes in the house with his teeth covered in poop, then when he plays with his toys, they get covered in it. or if he grabs your clothes, they get covered in it. i had to buy mint flavoured dog cookies. it is a horrible habit. the vet said he will outgrow this habit, and he is not lacking in vitamins or minerals. he is on a very good dog food, and is very healthy. she said many young dogs do this. i find it very distressing. i would welcome any advice as well to get him to stop. i am stressed right there with you.....
