Laziness or sickness?

Cookie doesn't like walking much. It may be simply because of his laziness, but I often get concerned that he might be feeling pain or some other sort of discomfort.

Cookie had an operation for a slipped disk in the neck in November 2007. At that time, we were very upset as he suddenly started to limp. In the hind sight, he seemed to have had some pain for several weeks, as he sometimes yelped when I touched his body. But, I didn't think that it was a sign of a serious condition like a slipped disk.

However, it seems there are some beagles like Cookie. Yesterday I came across a message thread titled "GU-U-TA-RA (lazy) beagles" in a beagle forum of a Japanese SNS site called Mixi. Maybe I don't need to worry too much, as Cookie doesn't mind walking if her girl friend, Bertie, is with him.
