The main reasons for hair loss include allergies, other primary dermatologic conditions, certain endocrine diseases, or self-inflicted trauma. Based on the look of the skin, it doesn't appear to be irritated or itchy.. Usually hair loss without itchiness is attributed to a systemic problem or something immune mediated in nature. Lastly, there are also some instances where dogs and/or cats can lose hair for no apparent reason without their being any sort of problem. To figure out the reason with certainty, some testing of the affected area would be required. If Bryant isn't showing any other problems right now and the area of effect is not growing in size, it isn't really an urgent thing to get checked out. Continue to monitor for changes and seek attention should the time come when it becomes necessary. Hope this makes sense.
