Labrador retrievers are the best service dog breeds because of their friendly and easygoing nature.
These dogs are hugely intelligent and can be trained quickly for beginners.
Golden retrievers are the prettiest service dogs with dense golden coats, and they are also easy to train.
German shepherds are the most loyal, intelligent, and fearless service dogs, great at learning tasks.
Poodles are also one of the most intelligent dog breeds and are great for people who suffer because of hypoallergenic coats.
Another friendly and loving dog breed with a tri-colored coat makes the best laid-back companion.
