Macadamia Nuts are Toxic to Dogs

As a veterinarian, I caution people about giving human food to dogs. That’s because dogs and people metabolize food differently. Macadamia nuts, raisins, grapes and sugar-free gums are some of the human foods that are toxic dogs.

Serotonin Syndrome in Dogs and Cats

Serotonin is a neurotransmitter found in the central nervous system (CNS) which includes the brain and spinal cord.  It is also in the peripheral nervous system which is basically, the rest of the body.

Zika Virus in Dogs and Cats

Zika virus was first discovered in Africa back in the 1940’s in a monkey with a mild fever. Since then, the disease has spread all over the world.

Chocolate Toxicity In Pets

Chocolate is one of the most common toxicities I see, especially around Christmas and Valentine’s Day. Pets climb counters to get to candy dishes and desserts. They also rip open boxes of chocolates wrapped as gifts. One of my patients, a cocker spaniel, ate a 5 pound box of dark chocolate that was left under the […]
