That sounds like fun. I suggest doing some "Side Hack and Side Car" searching. Maybe something will come up since side hack racing is still pretty popular.
I know on a Triumph site I am part of there have been several guys add side cars to their bikes. But they did not build them from scratch.

Dogs always prefer to go with you if you have to go.

I will add not sure of legality of adding a side car to a bike in this modern world controlled by insurance and lawyers.
There maybe set guidelines depending on the state you live.

Ray's right - Dog's love to go in whatever you are in. Our dog use to love to ride in the back of our side by side. She would not let you leave without here getting in the back.

Over here in the USA they are incredibly lenient to bikes being any state of modification and very little to stop anyone from riding just about anything on the roads. Most states are super easy to plate any dirt bike or ATV / UTV. Very little restrictions - except CA, because you know - it's CA....
