While there are some breeds that have a reputation for being a bit more laid back, I believe you’ll find more difference from dog to dog than in breeds. Find a reputable breeder/trainer of a dog you like the looks of and buy a fully trained 2/3 year old dog that has the personality you’re looking for. My last two dogs have been GSP’s and while both have been great hunting dogs, they are as different as night and day. I can attest that you can find a GSP to fit your needs. You might even look around for an older dog. I would avoid puppies.
