Thanks for all the quick replies.
Our dogs have never been crated so I am not sure if this would add to any problems they are already having. Like I said it just started happening, we have never had a problem with them being alone before. Can they suddenly become anxious about being alone??
Are they both spayed/neutered?
And yes, I believe that as dogs age they can develop anxieties as they age especially if they are begining to loose some hearing or sight. Digital the brindlewonerkid, for example is starting to go deaf, but he does hear some sounds. For some reason, now at 14 years old, the sound of me opening a coke can spooks him. No idea why and he has always been a very steady well-rounded dog that has been exposed to everything (has been a conformation, agility, rally, coursing, therapy dog with titles in all of those) and never spooked at anything. Just something about that sound now. No idea why, so I try very hard not to open beverage cans around him. Beer in a bottle or wine is fine
Also perhaps something outside is causing them to change their behaviors. Or something that happened outside yesterday has caused a change in today's behaviors. BUT you cannot address the behavior problems without first checking for a physical problem. This is very important to understand. If, by chance, your 11 year old has a bladder infection and you try to correct the problem, the behavior is going to become more ingrained (because he can't help it) and by the time you realize it is a physical problem, the physical problem may have become worse and the behavior has been practiced more often. And the more it is practiced, the harder it is to change. (easier to not begin smoking than it is to quit later on)
If you want to teach crating to a dog, i highly recommend Susan Garrett's dvd Crate Games.
