Spring is here and with spring we see buds popping out,
flowers beginning to blossom and our pets getting to spend more time enjoying
being outside. April is National Heartworm Awareness Month, and Salt Lake County Animal Services wants pet owners to be ready to protect their pets year round!
Spring brings with in an invasion of mosquito
larvae which grow to adults that spread heartworm disease from dog to dog and
cat to cat. A grown adult mosquito can drink 1 1/2 times their body weight. Salt Lake City is # 1 among the top 10 cities in the country
for a percentage increase in the number of dogs testing positive for the
Heartworm infection has been detected in all 50 states. In
January 2019 in the Salt Lake Area, 666 dogs were tested, of those only one dog
tested positive for heartworm. In February, 675 dogs were tested, 11 tested
positive. These may not be high numbers but there is an increasing prevalence
that is very concerning.
The disease is caused by a foot-long worm that lives in the
heart, lungs and associated blood vessels of the affected animal. When a
mosquito bites an infected animal and then bites an uninfected animal, the
larvae are deposited onto the surface of the animals’ skin and enter through
the wound. Once inside the host, it takes approximately 6 months for the larvae
to mature into adult heartworms. Once mature, heartworms can live for 5-7
years. This can cause lung disease, heart failure and damage to other organs.
If left untreated several hundred adults will infiltrate the heart and lungs
and eventually will result in death.
In the early stages of the disease, animals show few or no
symptoms. That’s why prevention is the best approach. Initial signs of
heartworm disease in dogs may include: Mild persistent cough, inactivity,
fatigue, loss of appetite and weight loss
Initial signs of heartworm disease in cats may include:
Coughing or asthma like symptoms, periodic vomiting, lack of appetite, and/or weight
It only takes one heartworm infected animal to substantially
increase the number of infected mosquitoes that can transmit heartworm
With changing climates that are extending the mosquitoes
breeding season heartworm disease in dogs and cats will only continue to rise.
There are currently 70 varieties of mosquitoes that spread heartworm disease.
Heartworm disease is almost 100% preventable. You will need
to have your dog or cat tested for heartworm disease before administering a
preventative. It is a simple test that is administered by your veterinarian.
The test requires a small blood sample and works by detecting the presence of
You need to test annually even if your animal is on a
preventative. The medicines are highly effective, but it is necessary to test
to confirm they are working. Heartworm disease is a dangerous and progressive
