Dog Panting During the SummerThe summer season is the time for you and your pets to get out of the house! However, sometimes with the busy schedules of vacations, cookouts, and visitation from out-of-town relative and friends, normal day-to-day tasks of life can be forgotten. Here are a few things to keep in mind this summer to keep your pets safe and healthy during this busy time of year.

What is Heartworm Disease?

Heartworm is a potentially fatal disease most commonly found in dogs. It is occasionally found in cats and ferrets and rarely found in humans. It is caused by worms that live in the heart and lungs causing heart failure and lung disease. They can also travel throughout the body, via the blood vessels, causing damage to other organs.

How is Heartworm Disease Transmitted?

heartworm-diagram-dogHeartworm disease is spread by mosquitos. When an animal infected with Heartworm is bitten by a mosquito, the mosquito picks up immature Heartworms (called microfilaria) in its blood meal. Once these microfilaria mature into larvae (over 10-14 days in the mosquito), they are transferred through the bite wound to the animal the mosquito bites for its next meal. These larvae then take approximately six months to mature into adult Heartworms.

What Are the Signs of Heartworm Disease in Dogs?

  • A persistent cough
  • Unwillingness to exercise
  • Fatigue after physical activity
  • Decreased appetite
  • Weight loss

digital dental pet x-rayWe've recently updated our dental surgical suite, which now includes digital dental radiographs!

Digital dental radiographs allow for the highest quality x-rays to assess your pet's teeth and oral hygiene. Even if your pet's teeth may look healthy, significant disease could be hidden below the gum line.

Our digital x-rays will allow our veterinarians to see below the gum line and asses an entire tooth as well as any roots that may be compromised.
