You can fly your wife out of the UK, no problem. The dog is a problem, as the current regulations for taking him out of the country (and back) require transport by an approved carrier. So, UK only for the dog, and please get him or her protective earwear, they are more noise sensitive than we are.
As to the type of aircraft, they will all go touring, but some take a long time.. �� Try to fly as many different types as you can, and remember is a buyer's market, so no rush!
