I'm thinking about getting a dog and I'm trying to decide what breed I want. I'm looking for a medium-sized dog that is easy to train. I want to take it hiking with me, so I want it to enjoy being with me and going on adventures. Give me a list of breeds that might fit my needs and general information about the breed.

Here are some active medium-sized dog breeds that would be a good fit for your active lifestyle:
1. English Springer Spaniel. Originally bred as hunters, these dogs are people pleasers, highly trainable, and very social. They don't enjoy being left home alone often, but they thrive when they receive attention and can spend quality time with their owners. They usually weigh around 40 to 50 pounds and have a medium-length coat that comes in a variety of colors.
2. Nova Scotia Duck Tolling Retriever. These pups look like they could be Golden Retriever's little brothers. They have red coats and usually weigh-in somewhere between 30-50 pounds. They enjoy being active and love swimming, and due to their retrieving background, they respond well to training. 
3. Whippet. Slender dogs that look like smaller versions of Greyhounds, Whippets are incredibly fast and need exercise every day. In between their energetic bursts, however, they are couch potatoes who love to snuggle with their owners. Their coloring is brindle and thanks to their short coat, they're very low-maintenance when it comes to grooming. They are very affectionate and content dogs. 
4. Australian Shepherd. When they get enough exercise, Australian Shepherds are great dogs that are low-key and easy to train. If they're neglected and cooped up too much, on the other hand, all of that extra energy gets channeled into destructive behaviors, like chewing and barking. They have thick coats that require regular brushing and grooming. 
5. Australian Cattle Dog. Often known as Blue Heelers, these powerful yet compact dogs need plenty of exercise. They love to explore and are incredibly energetic. They also tend to be very healthy dogs, so you shouldn't expect too many vet visits. Between their short coat and general health, these dogs are very low-maintenance - as long as they get the regular exercise they need!
