2 weeks ago I adopted a 4 year old lab/retreiver mix, she is awesome but I am having problem getting her to get in her kennel. She wasn't kennel trained when the foster parents took her in and they worked with her on it for a short period of time before I adopted her. For a week and a half I would say "get in your kennel" and she would go right in followed by a treat. Then all of a sudden she doesn't want to go in, she will just lay down wherever she is sitting. I try coaxing her with treats and that doesn't work. The only way I can get her in there is to pick her up and put her in front of the door. When she goes in I praise her and try to give her a treat but she won't even take it. I put in the treat before I close the door and the treat is still there when I let her out a couple hours later. All I get is sad eyes from her. Any suggestions? I don't keep her in the kennel for long periods of time.
