Our shepherd knew far no dog bed or basket. Recently, an incipient arthrosis was found. That is why we and others (drug therapy) opted for a dog bed. We have different models and recessions looked at. This model has convinced us. One could immediately notice their wellbeing. The bed seems to have a box spring property. Our dog has a shoulder height of about 62 cm. The size XXXL is optimal. You can sometimes make "long". Certainly a number would have been small enough, since they are anyway mostly bundling. The outer material seems durable. So a kind Gorotex. Can not comment on as we have recently only we. Price - performance ratio. Delivery Period was ok !!
