You might be surprised to discover how common dog worms are in the environment. In fact, some sources say most dogs - even healthy dogs -- host a low level of worms nearly all the time. After all, your dog goes outside, probably eats questionable substances on occasion, and may be known to roll in smelly areas. Since dog worms are often in the dirt (or in whatever else is in the dirt!) or are transmitted by fleas or mosquitos, you can see how it wouldn’t be a surprise that your dog could have worms.

April is National Heartworm Awareness Month! Are your pets protected? Here’s what you need to know.

Heartworms are transmitted by mosquitos.

Heartworms are long, spaghetti-like parasites that live in the heart or pulmonary arteries. These worms cause disease by clogging the heart and major blood vessels, resulting in reduced blood supply to other organs, such as the liver, kidney and lungs.
