So I got my parents a really nice puppy by an FC/AFC out of a 500 pt HRCH this past summer. She's 8 months old and smart, athletic, crazy about birds and everything you want in a dog. Great energy but once she comes in the house she's calm and quiet. I'm extremely excited to see how she turns out. The only problem is she isn't letting my folks know when she needs to go outside. She goes in the kennel every morning when they go to work and stays int here most nights. They come home from work at lunch every day to let her out. She runs and plays for about 20 min and goes number one but won't poop. They go inside, my folks ( one or the other is home but not both) grab something to eat and check emails, etc. and it never fails...poop by the from door. I think she's a little immature, but she's been an inside dog since they got her. She's really sweet and really smart. We just can't figure out what we're doing wrong.
Any help or ideas would greatly be appreciated.
