Obesity is currently one of the greatest health and welfare problems affecting domestic dogs and cats worldwide. Its impact extends beyond general health, directly influencing reproductive performance in both males and females. Obesity has been associated with reduced fertility, decreased litter sizes, and compromised survival of puppies and kittens.
Excess adipose tissue interferes with normal reproductive function by impairing ovulation, disrupting hormonal balance, and contributing to systemic inflammation and oxidative stress. These changes negatively affect gamete quality, conception rates, and overall reproductive outcomes.
In this webinar, we will explore the mechanisms by which obesity affects fertility in dogs and cats, review current evidence, and discuss the clinical implications for veterinary practitioners.
