High-volume surgery remains central to shelter medicine’s future
Bottom line
A new episode of Dr. Andy Roark’s podcast spotlights a familiar but increasingly urgent question in animal welfare: what role high-quality, high-volume surgery should play in the future of shelter medicine. In the conversation, Dr. Roark interviews Dr. Roberta Westbrook, a Houston shelter medicine leader, about the state of the field and where it may be headed next. The discussion lands at a moment when shelter medicine is expanding well beyond traditional brick-and-mortar shelter care into community outreach, access-to-care programs, and population-level interventions, while high-quality, high-volume spay/neuter remains a core tool for managing intake pressure and preventing homelessness.

Why it matters: For veterinary professionals, this is less about one podcast episode and more about a wider shift in how shelter medicine is defined. The field now spans population health, preventive care, support for pet parents, and community-based access programs, and high-quality, high-volume spay/neuter is still central to that model. That matters because the national spay/neuter system has not fully recovered to pre-pandemic output, according to the ASPCA, leaving shelters and community programs under continued strain.

What to watch: Expect continued debate over whether high-quality, high-volume surgery will remain primarily shelter-based or become more tightly integrated with broader community medicine and access-to-care models. (drandyroark.com)
Dr. Andy Roark’s latest shelter medicine discussion turns the spotlight on a question many veterinarians are already wrestling with: how high-quality, high-volume surgery fits into the future of animal welfare work. In the episode, Roark speaks with Dr. Roberta Westbrook, identified in public profiles as chief animal welfare and medical officer at the Houston SPCA, about the state of shelter medicine and where the profession may be heading.

That question comes at a time when shelter medicine’s scope is broader than many clinicians were taught in school. Merck Veterinary Manual describes modern shelter medicine as extending beyond municipal shelters and adoption agencies to include outreach clinics, trap-neuter-vaccinate-return efforts, disaster planning, support services for pet parents, and other community-facing programs. The Association of Shelter Veterinarians likewise frames spay/neuter work as part of a larger operational and medical system, not just a standalone surgery line. (merckvetmanual.com)
The timing also matters because high-quality, high-volume spay/neuter remains one of the field’s most scalable interventions. ASV’s spay/neuter guidance was developed to promote consistent, high-quality care across programs, and the ASPCA continues to position high-volume surgery as a key access-to-care and shelter-support strategy. In a June 2026 announcement about expanded national spay/neuter efforts, the ASPCA said affordable surgery output has not returned to pre-COVID levels, a gap that continues to affect shelter capacity and community animal populations.

That concern is consistent with earlier reporting and field data. In a 2022 Andy Roark podcast episode discussing pandemic-era overpopulation impacts, University of Florida shelter medicine faculty member Dr. Simone Guerios described spay/neuter as one of the most important long-term tools for reducing euthanasia and controlling pet overpopulation. The episode cites research using data from 212 clinics that showed a significant drop in surgeries during the pandemic period, reinforcing why current conversations about surgical capacity are not theoretical for shelters.

Industry context points in the same direction. PetSet, the Houston-based animal welfare organization linked to the episode’s guest network, says its grantmaking strategy is aimed at reducing intake, increasing access to care, and stabilizing the broader system through support for more than 114 organizations. That language reflects a growing view in shelter medicine that surgery capacity, community veterinary access, and shelter flow are interconnected rather than separate problems. (pet-set.org)
Expert commentary across the sector suggests the next phase may be more integrated, not less. The ASPCA’s community medicine programs combine affordable preventive care, minor illness treatment, diagnostics, and high-quality, high-volume spay/neuter in stationary and mobile settings, offering one model for how surgery can sit inside a broader access framework. Training programs at institutions such as UC Davis’ Koret Shelter Medicine Program and Cornell also continue to treat HQHVSN as a formal skill set tied to shelter operations, consultation, and population medicine.

Why it matters: For veterinary professionals, the takeaway is that shelter medicine is increasingly about systems design as much as individual patient care. High-quality, high-volume surgery still matters because it directly affects intake pressure, population control, and access for underserved pet parents. But the more important strategic shift may be that these surgeries are being discussed as one part of a wider continuum that includes community medicine, shelter capacity management, and public-health-oriented outreach. Practices, shelters, and nonprofit partners that can connect those dots may be better positioned to respond to ongoing demand and workforce constraints. (merckvetmanual.com)
What to watch: Watch for more investment in integrated community medicine models, more emphasis on HQHVSN training and operational standards, and continued discussion about where these services should live, inside shelters, in specialty surgery settings, or alongside first-line preventive care for pet parents.
