A. This is not. I am assuming that this dog has been with you for some time and this is a recent behaviour. Changes in behaviour can be due to many, many things, for example; (household) changes- has anyone recently moved in/out, stress-change in schedule, maybe you are working a new job/more hours, or there may be something that happened to scare the dog. All of these things require more detective work to unearth the problem, however, I would be more concerned that a health issue may be to blame. This potentially could be something very serious and I would recommend an immediate check up with your vet to rule out a medical cause. Once all medical issues have been cleared I would try to pin point potential other causes and the help of a trainer may be required. In some cases "old age" may be to blame but this should only be considered once everything else has been successfully eliminated. Some times old dogs just need a little more security and she may enjoy the comfort under the bed provides. If this is the case, your dog may enjoy having a dog crate (you can even remove the door) just to provide her very own safe space. Please book your dog a check up and good luck.
