Pet Carrier-----best GIVI box with hole cut in top and a couple of vent holes in rear.
My current dog Moose has been all over Europe, Korea, Hudson Bay to Central America. Works fine. GIVI box has over 500,000 miles. Hole has to be cut so his shoulders cannot pass thru. Box also worked for 2 previous Jack Russells. Last week 1600 miles in the high heat=no problems....for him
For Scooter Moose also likes to ride in bag I bought in Korea, that goes in well and held by velcro---probably warmer in winter.
