Medium Sized dogs are also in abundance in rescue centres. In fact, there are more medium sized dogs in rescue centres than large or small sized dogs.
There is a statistical reason for this. Most dogs are medium sized.
Now why would you want to get a dog that is deemed common?
Well, for one, most of the dogs that are considered highly intelligent belong to this size class. Take for example a German Shepherd or a Dalmatian. These two are commonly found serving alongside our modern heroes performing several tasks.
You also have the Labrador Retriever which is a very popular disability dog.
So, Medium may be common but there’s a wide range of breeds that you can choose from if you go with this size class!
