Bought medium for 7m Golden Retriever (24kg), it appeared to come up slightly smaller than the dimensions given - presumably that is because of the depth. Arrived quickly and looks robust. Initially Maggie was hesitant to use it (she was used to a soft lined bed with sides) but I squished out excess air to make it softer and placed the duvet in a cloth cover (single bed size more than adequate) this made it less of a contrast. She now sleeps on it quite happily and is less restricted when she stretches/turns over. We will try removing the cover in a few weeks ... Size wise, although she can currently lie flat out on it I anticipate buying the large size at a later date...

Great value and tough last longer than any other dog bed I've tried

I love this bed it slips under a worktop in my kitchen, it is waterproof and comfortably. It can be wiped of and kept clean, so no smelly material.
