Dog Bed

Hi everyone! I'm a resident of Texas, USA and an owner of 8 months old pug. I love my pug to death and want him to give the best for playing, eating and sleeping. I'm planning to buy a Dog bed for him. Now, I'm confused about the ideal size of dog bed that I should get for him and the material of dog bed that i should opt for so that my pug gets an easy and peaceful sleep. Please come up with the solution to my problem and also suggest me the stores from where I can buy the best quality dog bed? Money is not a concern. Thanks in advance!
