In each issue of Today’s Veterinary Practice, Pet Health by the Numbers correlates article topics with statistics provided by Banfield Pet Hospital (banfield.com). These statistics are extracted from data collected from the medical records of nearly 2.3 million dogs and 470,000 cats presented to more than 850 Banfield Pet Hospitals in 2013. Learn more about data collection by reading Welcome to Pet Health by the Numbers (January/February 2014 issue) and Key Findings from the State of Pet Health 2014 Report (May/June 2014 issue), both available at tvpjournal.com.

The following tables outline the prevalence of ticks in dogs and cats presented to Banfield Pet Hospitals in 2013. Mites and ticks are discussed in Canine Arthropods: Mites & Ticks Recommendations from the Companion Animal Parasite Council.

Prevalence of Ticks by U.S. Climate Region (2013)

Banfield 3-15

Region with Greatest Prevalence of Ticks by Patient Age* (2013)

Banfield 3-15

* NOTE: Age group totals will not match overall totals. Age groups are derived from visit age in 2013; some pets may have been counted in multiple age categories (eg, a pet that visited as a juvenile and then as a young adult in 2013).

 

Path to Pet Wellness: This dataset confirms that ticks infest pets throughout the United States, and the geographic trends resemble those of previous, similarly conducted surveys.1 However, these data are generated from point observations in clinic, an approach that does not accurately capture the episodic nature of tick activity. As such, the prevalence values dramatically underrepresent actual tick risk.

Ticks feed for only a few weeks of their 2-year life span. Dogs and cats presenting with a serious, potentially fatal tick-borne disease often do not have a tick attached at examination.2-4 Failing to find ticks at a single observation should not be interpreted as absence of infestation risk. Surveys conducted using antibodies to tick-borne disease agents as a proxy for past tick infestations provide a more accurate estimate of risk, and document higher regional prevalence at 0.9% to 13.3%.5

The Companion Animal Parasite Council recommends consistent use of tick control on pets to protect them from ticks and tick-borne infections.6
