XC90 loading area and dog

Hello everyone, I have looked at the XC90 7-seater in the sales room today. Everything is very nice variable, lots of space and finely processed. However, I noticed that the loading area is quite high compared to ML or Touareg. I have a low-built Labrador and am not sure if I can teach him to jump up there by myself. (currently the animal is used to a normal family combi). And the 30 kg each time there is no alternative for me…. Do the dog owners among you experience this? Could that be a problem? Greeting Alani
