I should know the answer to this really but want some opinions. I'm in the process of buying my boys a new bed because we have dug out a little drop front bed from when Alfie was a puppy and they are both squeezing into this and snuggling up favouring it to their big tuffies bed :-?  I think they prefer a bed with sides instead of the matress type bed and I have discovered this -

My problem is, I don't know what size to go for. Do I go for the biggest bed which is 97cm x 74cm which is huge or would the next size down at 76cm x 64cm be big enough for two Cavaliers? I'm going off the fact that they would rather squeeze into this minute bed we have here than stretch out....or is it better to get the biggest size then they have the choice to either sprawl out or snuggle together in a corner. There is quite a large price difference between the two sizes so I don't want to throw money away if its not necessary.
