Thanks for the suggestions. They have already lost all their puppy teeth, but I do think they are bored. They do come inside almost everyday, but when they do come in, all they want to do is sleep.
I got the pups way before Charlie passed. I never even thought that that could be one reason they are misbehaving. Charlie helped enforce the rules. They still got into things, but not as much as they do now.
I am going to get the enrolled in the next step in the obeidence classes, but for now, I think I will just have to get out and play with them more.
