28. Chesapeake Bay Retriever
Chesapeake Bay Retrievers are commonly referred to as “Chessies.” Their ability to learn new skills quickly have made them known to be some of the most intelligent dog breeds in the world. They tend to be used as hunting dogs in order to take advantage of their smart instincts.
27. Cardigan Welsh Corgi
The Cardigan Welsh Corgi is known for its short little legs and large upright ears. Similar to the Pembroke Welsh Corgi, it is one of the oldest breeds originating from the British Isles. The breed is ranked in the “second tier” of dog intelligence, meaning that they require only between 5 to 10 repetitions to learn new commands and respond to them about 85% of the time.
