Testosterone & Singing

Singing and testosterone
In male birds the secretion of testosterone, the male hormone, stimulates growth of brain areas that influence singing.

Do you think testosterone influences vocalization in dogs, cats, and other pets? If so, intact pets that still have their testicles should be more vocal than neutered pets. Pets neutered later in life should vocalize better than those neutered early.

In the next few blogs entries we'll examine the effects of early spaying and neuteing on pets. Not all the effects are positive. Most are far more important than singing, barking, yeowling and other forms of vocalizing.
