6. Goldendoodle
A Goldendoodle is a crossbreed between a Golden Retriever and a Poodle. The temperament of a Goldendoodle depends on how well socialized it is, as well as the genes the puppy inherits from the parents. You can easily see this when a puppy would let you approach him which is a good sign of its social skills. Positive reinforcement is also the key for training, so that a Goldendoodle can absorb what it learns. This crossbreed is smart and highly trainable.
