According to the U.S. Food & Drug Administration, heartworms have been reported in dogs in all 50 states, which means all dogs are at risk of contracting heartworm disease. Heartworms, or Dirofilaria immitis, are transferred from infected mosquitoes to your beloved pet when the insect bites your dog.

A pup with heartworms can suffer heart failure, organ damage, lung disease and even death. Since you likely won’t know that your canine has had any contact with an infected mosquito, learn all you can about heartworms and how to prevent them. After all, prevention is the most important thing you can do.

How Heartworms Operate

Heartworms only measure 1/100th of an inch long, but they do a lot of damage over the course of their lifetime. Once inside your dog's body, the heartworms travel to the heart via the bloodstream. They then begin to grow and produce offspring. It’s not uncommon to find up to 15 heartworms, measuring up to 12 inches long, inside a dog.

Symptoms of a Heartworm Infection

While a dog with a heartworm infection may not initially show symptoms, they will begin to suffer the longer the infection is allowed to continue.

The first thing you'll notice is your once energetic friend no longer wants to go outside to exercise. They may become tired after a little physical activity and their appetite may decrease, which can lead to weight loss. Next, the dog will develop a cough that just won't go away.

As the infection becomes more serious, you may notice your pet has a swollen abdomen, abnormal lung sounds and a weak pulse. The pup may even pass out at times, as their blood flow becomes restricted.

The last sign of a heartworm problem is the diagnosis of caval syndrome. This syndrome shows up through pale gums, urine that resembles the color of coffee and difficulty breathing.

How to Prevent Heartworms

Heartworms are not contagious; a dog cannot transfer the worms to another dog. A pup can only become infested with the heartworms if they are bitten by an infected mosquito, so you do not need to separate your animals if one tests positive to prevent the other one from getting sick.

A Macrocyclic Lactone medication effectively kills heartworm larvae before they have a chance to mature into adults. Your veterinarian will use this type of medicine to prevent a heartworm infestation.

You need to give your dog the heartworm preventative once per month throughout the duration of their life. You can give this medication along with the pet's monthly flea treatment to keep the pup healthy. Doing this together will hopefully help you remember.

What to Do If Your Dog is Already Sick with Heartworms

If your dog was not on a regimen to prevent heartworms and you notice they exhibit the symptoms mentioned above, your veterinarian will first need to run a few tests to confirm the disease. These tests include blood work, a radiograph, an ultrasound and an echocardiogram.

Once heartworms are confirmed, your dog will be given Immiticide, which is the only drug available in America to treat mature heartworms. If your pet is not responsive to this medication or already quite sick, the veterinarian may recommend surgery to physically remove the worms from your pet's heart.

Canine parvovirus (or just parvo) is an extremely contagious disease that any dog can get, but puppies in particular are most susceptible due to their young immune systems. The illness is gastrointestinal in nature and can be fatal if not treated early in your young dog.

Canine parvovirus is spread by infected dogs who come in contact with healthy dogs or if a person handles infected feces and goes around a healthy dog. Vaccinations to prevent canine parvovirus infection begin at less than two months of age and are given in a series of shots until a puppy reaches around four months old.

If your puppy is exposed to canine parvovirus in any way, they can become infected and will quickly become ill, especially if your dog has not received their full series of vaccinations for the virus. The following are signs your puppy has parvo. If any of these signs apply to your young pup, take them to the vet right away for diagnosis and treatment. Parvo can be fatal if not treated within 48 to 72 hours.
