We received a 9 week old all black german shepherd puppy from a breeder on Saturday (12/1/18). She told us the puppy was pee pad trained. We decided immediately to crate train instead of using the pads. We are new dog owners by the way. We were told to feed the puppy in the crate, wait 10 minutes, bring them outside and say "Go Potty". The puppy would poop/pee and then we bring him inside and play with him. However, this has not happened. We bring him outside and he is not interested at all in pooping or peeing. We are out there 20 minutes, 30 minutes. Eventually he will pee, but rarely poop. We praise him, give him a treat. He is happy, does an occasional sniff, eats pine straw or sits at our feet. We pick him up, put him back in the crate, wait 25 - 45 minutes and bring him back out again. He does the same thing. He rarely poops. Last night he ate dinner at 6:30 pm, spent the night in his crate without making any sounds all night. We woke up at 6 am, put him on the leash, carried him to the grass and told him to potty. He peed, 20 minutes later still no poop. We brought him inside and fed him breakfast. He ate, drank a little water and then sniffed around the house as usual and then started POOPING in the family room. We told him no, rushed him outside (with poop dropping as we carried him). We brought him in, put him in the crate for 45 mins and then took him out. He was outside for 20 mins, no poop, just pee. How do we get him to poop?
