Living in California’s Central Valley offers dogs warm sunshine, open spaces, and an active outdoor lifestyle. However, the region’s unique climate and environment also put pets at risk for certain health conditions. At Riverpark Pet Hospital in Fresno, we believe prevention and early detection are key to keeping your furry family members healthy.
Below, we’ll review some of the most common diseases affecting dogs in the Central Valley and share how you can protect your pet.

Q&A: Dog Health in Central Valley

A: Yes. Parvovirus remains a major concern in Central Valley communities. Puppies and unvaccinated dogs are especially vulnerable. Keeping your pet up to date on vaccines is essential.
