Look into golden retrievers or labradors. Smart dogs that are easily trained. They’re also friendly as fuck and just generally great dogs.
Dogs are fantastic companions and great animals with a lot of love to give. Owning one is a commitment to that dog for it’s entire life, so picking one that suits your lifestyle is very important. Because otherwise it’s not fair to the animal, who’ll basically be loving you unconditionally. If you’re getting a dog you’ve got to be all in on giving it the best life possible, so it’s not something to be taken lightly.
