I was doing some research on neutering, and I found this:

1) Loss of testosterone as a result of desexing may result in immature development of masculine characteristics and a reduced body musculature
The testicles are responsible for producing testosterone: the hormone that makes male animals look and act like male animals. It is the testicles that make male animals develop the kinds of masculine, testosterone-dependent body characteristics normally attributed to an entire animal. These include: increased muscle size and development; reduced body fat
; mature penis development; mature prepuce development (mature penis sheath development); the ability to extrude the penis from the sheath (prepuce) and the suppression of development of feminine characteristics (mammary gland development, milk production etc.). Desexing, particularly early age desexing, may limit the development of mature masculine features such that they remain immature and juvenile looking and cause the neutered animal to have a reduced muscle mass and strength compared to an entire animal of the same size and breeding.

I know each breed tends to age differently, but, I don't think neutering at 6 months is good based on the research that I did. Also, neutered dogs need about 25% less calories than intact dogs because testosterone burns a lot of calories.
