Female dogs in heat go through hormonal changes and behavior shifts.

Spaying is more than birth control—it’s a lifesaving medical procedure. It prevents painful conditions, improves behavior, and gives your dog a healthier, longer life. It’s one of the best decisions you can make.
When done early and under vet supervision, spaying is safe and routine. Your dog won’t “miss out” on anything—in fact, she’ll thrive without the risks of heat, pregnancy, or hormonal distress.
