Introduction
Dogs, our loyal and faithful companions, are unfortunately susceptible to a variety of parasites. These unwelcome guests, ranging from fleas and ticks to heartworms and intestinal worms, can affect dogs significantly and cause serious health problems.
This guide aims to shed light on what a dog parasite is, its potential dangers, and, importantly, how to prevent and treat parasites in dogs. With the right measures, we can ensure the well-being of our pets and keep their tails wagging joyfully.
Why is it important to prevent parasites in my dog?
Parasites can not only cause discomfort and pain to infected dogs but also bring about serious health implications. If left untreated, these parasites can cause anemia, intestinal blockage, lack of appetite, or even death in extreme cases.
Furthermore, some parasites are zoonotic diseases – that is to say, they can be transmitted from infected dogs to people. Therefore, it is essential to be diligent in taking preventive measures and promptly treating any infestations that may occur in an infected dog.
Common Parasites in Dogs
Ticks
Ticks are small arachnids that feed on the blood of their hosts. They can transmit dangerous tick-borne diseases like Lyme disease and Rocky Mountain spotted fever. Dogs can often contract parasites such as ticks from being outside in grassy areas with lots of long grass.
Fleas
Fleas are tiny parasitic insects that feed on the blood of their hosts, adult dogs. Dogs may suffer from various skin reactions due to flea bites, including severe itching, hair loss, and skin infections. An infected flea can also create serious health problems, as infected fleas carry other parasites, such as tapeworms.
Intestinal worms
Intestinal worms are parasites that live in the intestines and can cause diarrhea, vomiting, or weight loss. The most common types of intestinal parasites are roundworms, hookworms, whipworms and tapeworms:
Roundworms
Roundworms, which are also known as Ascaris, are the most common type of parasitic worms found in dogs. They can grow to be quite large and may cause vomiting and diarrhea.
Hookworms
Hookworms live in the intestines and feed on blood. Symptoms may include severe anemia and, weight loss, bloody feces, and vomiting.
Whipworms
Whipworms are small, threadlike parasites that can cause intestinal issues such as diarrhea and weight loss in dogs.
Heartworms
Heartworms are malicious parasites that can live in the heart, lungs and associated blood vessels of dogs (and cats). These worms are originally transmitted by coming in contact with an infected mosquito.
Heartworm disease, in severe cases, can cause lasting damage to the cardiovascular system if left untreated. Symptoms of heartworm infection include coughing, weight loss, and decreased appetite.
Identifying Parasite Infestation
Common symptoms suggesting a possible parasite infestation include:
Gastrointestinal upset
If your dog is experiencing frequent bouts of diarrhea, and vomiting, or seems to have an unusually upset stomach, it could be a sign of an internal parasitic infestation. Internal parasites often reside in the intestines and can disrupt the digestive system.
Some dogs may also display changes in their stool, such as consistency or color. These symptoms require immediate attention and consultation from a veterinarian.
Weight loss
Parasitic infestations can cause weight loss in dogs due to the parasites’ ability to absorb nutrients meant for the dog. If your dog has been losing weight without any other changes (i.e., diet, exercise), then it’s important to have them tested for parasites.
Skin issues
Rashes, itching, hair loss, and other skin irritations can be signs of an infection caused by external parasites. External parasites such as fleas and ticks are the most common dog parasites known to cause skin irritation in dogs. Ear mites can also cause skin issues, such as itchy, red, and waxy ears; however, ear mites usually only affect young puppies.
If your dog is suffering from skin issues due to a parasite infection, then supplementing its diet with vitamins can help maintain healthy skin while receiving treatment.
Coughing or difficulty breathing
If your dog is frequently coughing or having difficulty breathing, then it may be a sign of early stages of heartworm infestation. Adult heartworms can cause serious damage to the lungs and heart if left untreated, which is why it's important to take your dog immediately to the vet if you notice any respiratory symptoms.
Lack of appetite
Loss of appetite can be a sign of several health issues, including parasites. If your dog has an otherwise healthy diet and suddenly refuses to eat, you might want to have them tested for parasites.
Anemia
Anemia can be a sign of hookworm infestation as these parasites feed on the blood of their hosts. Anemia is characterized by pale gums, lack of energy and poor coat condition.
Skin lesions
Skin lesions can be caused by a variety of parasites, including fleas and ticks. These lesions may appear as red bumps or scabs on the dog's body.
Vomiting of worms
Vomiting out worms is a sign of roundworm infestation. This type of parasite can grow to be quite large and can cause discomfort if left untreated.
Behavior changes such as lethargy or aggression
Parasites can cause a variety of behavior changes in dogs, such as lethargy and aggression. If you’ve noticed any unusual changes in your dog’s behavior, it may be a sign of a parasitic infestation.
Prevention of Parasites in Dogs
Regular flea and tick treatments
Flea and tick treatments should be part of your regular grooming routine. Speak to your veterinarian about the best product for your dog and make sure to use it as per the instructions.
Keeping your dog’s environment clean
Keeping your yard and home clean can help reduce the risk of parasites. Mow the grass regularly, pick up any debris, and keep your pet away from areas where wild animals congregate.
Regular vet visits
Regular checkups with a veterinarian are essential for preventing parasites in dogs. During these visits, the vet will be able to identify any clinical signs of parasites and recommend treatment.
Avoiding contact with sick animals
Parasites can be spread from one animal to another, so avoid contact with stray or unknown animals. If you do come into contact with them, make sure to thoroughly wash your hands and keep your dog away from them.
Proper sanitation
Practice proper sanitation when dealing with any pet waste or contaminated materials. Make sure to wear gloves, wash your hands thoroughly, and dispose of any material in a sealed bag.
Heartworm prevention strategies
Heartworms are spread by mosquitoes, so make sure to use a heartworm preventative medication as directed by your veterinarian. Also, keep your dog away from areas where standing water accumulates (e.g., puddles, ponds) and regularly check for any signs of mosquito activity in your area.
Feeding high-quality food
Feeding your dog a high-quality diet can help support its immune system and reduce the risk of parasites. Choose foods that are rich in protein, wholesome grains, vitamins, and minerals.
Regular grooming and baths
Regular brushing and baths will help remove any parasites that may be on your dog’s skin or coat. The best shampoo to use if your dog has a parasitic infection is a high-quality Chlorhexidine shampoo, as these shampoos will help relieve itchiness and skin infections.
Helpful Options for Parasite Infestations
Understanding vet-prescribed treatments
It's important to understand the treatments prescribed by your vet. They may include deworming medications, flea or tick preventatives, and other parasite prevention strategies. Make sure to follow their instructions carefully and never skip any doses.
Over-the-counter treatments: effectiveness and safety
Over-the-counter treatments can be effective, but always read the instructions carefully and use them as directed. Speak to your veterinarian about any questions you have regarding over-the-counter treatments before using them.

Once your dog has been treated for parasites, follow up with regular vet visits and maintain a routine of parasite prevention strategies. Make sure to continue using flea and tick treatments as prescribed, practice proper sanitation around pet waste, and keep your home and yard clean. This will help reduce the risk of future infestations.
