Also my dogs go with me everywhere. How am I to fit them in
the car, on the motorbike, in the tractor etc all at the same time!

Get a bigger bike mate!
I used to carry a big stag bitch and a 30 inch stag dog on my bike.one on the tank the other on a platform over the rear wheel mate,though i didnt like the slobber from a hard run dog going down the back of my neck hahaha.

Lets go back to the foxy cross mate.
