There are dog beds in the pet shop. Most are fancy with colors and design. We bought one for our small dog and also for our bigger dog. But the bigger dog prefers to sleep on the wooden floor of our bedroom. Now it is shown in the picture that our bigger dog is comfortable with the towel as his bed.
Pets have their own idiosyncrasies that we cannot force on them what we think is good for them. If they like it then okay but if they do not like it then try another one.
Do you buy your dog an expensive bed?
