I have a Cardigan corgi and a Pembroke both under 40 pounds. After 2 months of being used by them to get on and off my bed the wood split along the edges and has caused the ramp to have a weak spot in the very center of the ramp where the seem connects the 2 pieces of the ramp. Very happy with purchase and ramp seemed sturdy. Contacted seller about ramp weakness/design flaw and even though we were outside the time frame for return the seller replaced the ramp with a new one. Awesome customer service!
