It’s no surprise that a German shepherd is the second most popular dog breed because they’re courageous, confident, and smart. They are excellent all-purpose workers and are used in a number of specialized situations as police dogs or service dogs. German shepherds don’t always give affection lightly, but they are fiercely loyal family dogs that are great with kids.
Golden retrievers are intelligent, friendly, and devoted sporting dogs. Goldens take their jobs to heart and try to be the best at what they do, whether it’s hunting, serving as a seeing-eye dog, working in search-and-rescue, or simply being a loving companion.
Besides strength, endurance, and speed, Doberman pinschers have the smarts necessary to retain training in order to be an in-demand police dog or war dog. There is even a bronze Doberman pinscher statue titled “Always Faithful” at the National War Dog Cemetery in Guam to honor the dogs — mostly Dobermans — that were killed in service during the Second Battle of Guam in 1944.
The Shetland sheepdog is basically a miniature working collie. They are playful and intelligent herding dogs that love to learn new tricks and play with kids. Shelties are affectionate and loyal with their families. But they’re also great watchdogs because they are reserved towards strangers and have a tendency to bark at people.
