Many dogs are really not good for house or backyard dogs. Goldens, Labs, and other retrievers and hunting type dogs are much happier on a farm where they can run free and chase cows and stuff.
I have a Golden that I love to death, but I might give her to a friend who lives in the country and loves his dogs.
As for giving it all up, sell everything or give it away. I just bought a sailboat. It is famously seaworthy and cheaper by a longshot than a new car. This model of boat has done countless ocean crossings and quite a few circumnavigations. You can find them for less than ten grand and put in the work necessary.
1973 Albin Vega. Totally beefed up. I don't have the dodger or windvane installed. I'll do that this summer.
