I have a 7 month old Weimaraner mix. She is crate trained. I had a 42" crate from my older dog and after the puppy started doing her business in there while crated during the day, I bought a 36" crate with a divider. She was doing well. Now, she will GO into her crate and poop. She's pooped on my couch. She doesn't make it through the night anymore. She has pooped while standing next to my mom in her kitchen. I have not changed the dogs routine. Her stools are firm. I am about to lose my mind. I need help on why she has started doing this!
