Feline drug may lead to new Covid-19 treatment

Researchers at Anavive, a pet health drug discovery and commercialization company, are seeking approval to test a new drug for Covid-19 that was originally developed to treat feline intestinal coronavirus. Similar to Covid-19, feline coronavirus is very contagious. In some cats, the virus mutates and leads to feline infectious peritonitis (FIP), which is currently the top cause of death for young cats and kittens (~700,000 cats annually). The new drug, […]

Dogs may facilitate spread of Rocky Mountain Spotted Fever

Alec Oliva, a graduate student at Midwestern University – Glendale campus, presented research examining the spread of Rocky Mountain Spotted Fever (RMSF) at the 2019 Arizona Physiological Society conference this past weekend. With a mortality rate as much as 80% without treatment, the spread of this disease is quite concerning. Ticks are vectors for the Rickettsia rickettsii bacteria responsible for causing RMSF. Dogs are notoriously at risk for acquiring tick infestations […]

Ultrasonic rats

Dr. Charles Schaefer, a postdoctoral fellow working with Dr. Tobias Riede at Midwestern University presented research at the conference examining how rats use deep breaths to produce ultrasonic vocalizations. Similarly, researchers have studied a variety of vocalizations in rats that signify positive as well as negative emotions and how their brains process this information. Did you know rats enjoy being tickled?

Chronic stress impacts everyone around us

A new study examined how our stress impacts our best friend’s mental health.  The researchers studied Shetland sheepdogs, border collies and their owners and found that dogs living with people who had high levels of stress hormone (cortisol) in their hair follicles, similarly had high levels of cortisol in their fur. In contrast, canine anxiety does not appear to run off on people. That’s good news for those of us […]
