X3 (or X5) and Big Breed Dogs??

[PeterNYC]

hello all....

I just placed on order for an x3 (will arrive in June...yippie!!) and we have a chocolate lab puppy (who will soon grown into a big dog)

Just curious if there are other X owners with dogs who have recommendations for where their dogs ride when in the X.....the back cargo area seems good, but I guess some may use the back seat with a 'dog seat belt' (if there such is available for Xs)

Any big dog owners have advice or experience in this matter? Are there any recommended after market products?

We were thinking of getting the non-skid mat (or some form of cover) for the back cargo area for when she gets older (as a pup she rides in her crate or in a lap)

Thanks in advance
