Explanation: In the 1970s the Boston Consulting Group (BCG) created the BCG Growth - Share matrix that consists of 4 categories. The aim of this matrix is to manage various business units within BCG. A dog is a business unit within a mature industry, that has a small market share in said industry. A dog doesn't need a large initial investment, and as a result doesn't accumulate strong cash flows over time for BCG.

In most cases closing down divisions in this sector is the logical choice. This is because dogs are usually of lower value compared to other investements, and the capital used in these types of investements can be used in other parts of the business. Thus they carry low growth markets have relatively low market shares.
