It is finally getting warmer and the sun is shining again – but unfortunately, the beautiful weather doesn't just lure us and our four-legged friends outside. Parasites that can spoil spring for dogs are also becoming increasingly active.
A lovely walk in nature can quickly end with a "souvenir" that is annoying and dangerous to boot. So that you can react correctly in an emergency or, better yet, prevent it from happening at all, we have put together the most important information for you.
In this article, you will learn which parasites are increasingly prevalent in dogs during spring, how to recognize them, and which diseases they transmit. We will also give you helpful tips on how to protect your dog from parasites.
1. Ticks
Ticks are tiny arachnids that attach themselves to the skin to feed on blood. In Germany and Switzerland, the common wood tick, the ornate cow tick, and the brown dog tick are particularly common.
These parasites can infest your dog even before the official start of spring. Ticks lurk in forests and meadows, as well as in your own garden, from February to November. They sit on grasses, shrubs, and other plants up to about 1.50 meters high.
Your dog can brush off a tick as they pass by, but these bloodsuckers can also drop onto their "prey" from above. Once they have arrived, they look for a protected spot with thin skin. Popular areas include the head, ears, armpits, groin, paws, and genital area.
The tiny parasites are very difficult to spot in dense dog fur. Furthermore, a tick bite on a dog often goes unnoticed because it causes no pain and does not itch. Ticks often simply fall off again after they have gorged themselves.
The tick bite itself is not dangerous to the dog, but ticks can transmit serious, sometimes life-threatening diseases.
Lyme disease
In the initial stage, Lyme disease manifests through symptoms such as fever, loss of appetite, lethargy, joint pain, lameness, and swollen lymph nodes.
Left untreated, Lyme disease can lead to chronic inflammation in dogs, particularly in the joints and kidneys. Permanent neurological damage can also occur.
Vaccination against Lyme disease is possible, but it only offers partial protection and is controversial.
Anaplasmosis
Dogs infected with anaplasmosis show symptoms such as fever, fatigue, loss of appetite, enlarged lymph nodes, nosebleeds, and pinpoint mucosal hemorrhages. Lameness and swollen joints are also common.
Other possible symptoms of anaplasmosis in dogs include stumbling, muscle tremors, seizures, vomiting, diarrhea, and weight loss.
Babesiosis
This disease is also known as "dog malaria" because it destroys red blood cells.
The symptoms of babesiosis in dogs range from fever, dullness, and loss of appetite to dark red or brown urine, pale mucous membranes, and weight loss.
Serious consequences such as anemia, jaundice, shortness of breath, and organ failure are also possible. If left untreated, babesiosis is often fatal.
There is a vaccination against babesiosis, but it does not prevent infection; it only reduces the severity of the symptoms.
Ehrlichiosis
An infection with the ehrlichiosis pathogen goes through three phases without treatment. In the acute phase of ehrlichiosis, the dog has a fever, suffers from weakness, nosebleeds, swollen lymph nodes, and anemia.
The subacute phase is characterized by less visible symptoms as the infection settles into the spleen.
In the chronic phase, blood count changes, joint inflammation, kidney problems, lameness, and eye problems (up to blindness) occur.
Ehrlichiosis is transmitted by the brown dog tick. Originally from warmer regions, it is increasingly appearing in Germany and Switzerland due to climate change.
How can you protect your dog from ticks?
There are various methods to avoid infections caused by ticks in dogs.
Tick collars, tablets, or spot-ons (preparations applied directly to the skin) can keep ticks away, so that in an ideal case, no infestation occurs at all.
Instead of these chemical products, you can also use natural remedies:
- Massage coconut oil into your dog's coat or mix it into their food.
- Dilute some black cumin oil and add it to their food.
- Essential oils like lemon eucalyptus or geraniol can be applied to the coat when highly diluted. However, caution is advised due to potential intolerances.
Examine your dog thoroughly after every walk and stay outdoors – even if you have used tick protection.
If you discover a tick on your dog, carefully pull it out with a tick remover. Make sure not to squeeze the tick and ensure the head does not get stuck. Afterward, place the tick in disinfectant or high-proof alcohol to kill it. Also, immediately disinfect the area of skin where the tick had attached itself and monitor it closely for the next few days.
Also, watch for symptoms of illness in your dog. If you are unsure, contact your veterinarian as a precaution.
2. Harvest Mites
While other types of mites, such as mange, ear, or hair follicle mites, occur year-round, harvest mites are active from March onwards. As the name suggests, the microscopic, orange-colored mites sit in the grass in meadows and gardens.
Your dog can pick up these parasites in spring from grass, for example, when running across a meadow or rolling around, allowing them to nest on their skin.
Symptoms of harvest mites in dogs include red spots and itching in the affected areas – usually the paws and abdomen.
What to do about harvest mites in dogs?
If your dog shows these symptoms, you should have a skin sample analyzed by a veterinarian to be sure which type of mite it is.
While harvest mites are unpleasant, they are harmless compared to mange mites. Furthermore, mange mites can be transmitted to other dogs and humans, whereas harvest mites are only transmitted through direct contact with infested grass.
Nevertheless, a harvest mite infestation in dogs must be treated, as it can cause severe skin irritation and inflammation. As a rule, special mite shampoos are sufficient, but in particularly severe cases, medical treatment may be necessary.
How can you protect your dog from harvest mites?
Anti-parasite collars, mite sprays, or spot-ons can be helpful in warding off harvest mites.
However, there are also natural remedies:
- Coconut oil massaged into the coat can deter harvest mites.
- Alternatively, you can rub diluted neem oil into the coat.
- Apple cider vinegar forms a protective layer on the skin that can keep mites away and relieves itching.
- Natural anti-harvest mite sprays are also available commercially.
In any case, it is important to check your dog's coat and skin daily, especially after they have been outside.
It is also recommended to wash your dog's blankets, cushions, and stuffed toys at short intervals during spring and summer. Household textiles should also be cleaned regularly.
3. Fleas
Although fleas are active year-round, these parasites also become a growing danger for dogs in the spring.
On one hand, the likelihood of infestation is higher the more time your dog spends outdoors and interacting with other dogs. On the other hand, fleas also love warm temperatures, reproduce more strongly, and can survive outdoors for a while without a host.
Therefore, the probability of your dog being infested with fleas is higher in spring and summer than in other seasons.
Dangers of fleas for dogs
Fleas are not only very uncomfortable for dogs but also a serious threat.
The tiny parasites live in the dog's coat and feed on their blood. In doing so, they cause severe itching, which can lead to irritated skin and skin inflammation.
In particular, flea bites can trigger flea allergy dermatitis in dogs. This manifests as a red, inflamed skin rash that itches, burns, and is painful. Flea allergy dermatitis can significantly impair your dog's quality of life, and the inflamed areas can become infected with bacteria.
An even greater danger from fleas to dogs, however, is tapeworms. Fleas can ingest tapeworm eggs from infected feces and transmit the larvae that develop from them. The double-pored dog tapeworm is particularly common in dogs.
If your dog licks their fur due to itching and swallows a flea, the tapeworm larva enters the gastrointestinal tract. There, the tapeworm settles and causes symptoms such as itching at the anus (often recognizable by "scooting"), emaciation, loss of appetite, diarrhea, or vomiting.
How can you protect your dog from fleas?
The same applies to fleas: it is best if an infestation does not happen in the first place. Flea collars, flea tablets, or spot-ons can be effective methods for deterring fleas.
Natural alternatives include, for example:
- Coconut oil – it can not only deter fleas but also destroy their exoskeleton.
- Neem oil can be used for prevention or to treat itching from flea bites.
- Lemon juice and vinegar, diluted with water and sprayed into the coat, create a mixture that fleas cannot stand.
- Rosemary spray can also have a repellent effect on fleas. You can easily make it by boiling rosemary sprigs in water, letting it cool down, and filling it into a spray bottle.
To detect parasites in your dog's coat early, examine them carefully after every stay outdoors.
If you discover fleas or flea eggs, comb them out carefully with a special flea comb. With a heavier infestation, it is often necessary to bathe the dog with flea shampoo. Also, clean textiles that your dog has contact with at short intervals.
Also watch for symptoms like itching, skin redness, rash, lethargy, scooting, and gastrointestinal issues. If you see signs of flea allergy dermatitis or a tapeworm infestation, take your dog to the veterinarian.
4. Worms
In addition to tapeworm species such as the double-pored dog tapeworm, there are other worms that can be dangerous to your dog, particularly roundworms and hookworms.
They occur year-round, but dogs can easily pick up these parasites, especially in spring. Worm eggs can survive longer in mild weather in infected feces, soil, animal carcasses, or on blades of grass.
Dangers from worms in dogs
If your dog eats something while out and about or brushes against worm eggs with their body and then licks their fur, the eggs reach their digestive tract. Both tapeworms and roundworms/hookworms are parasites that live in the dog's intestines.
Symptoms of a worm infestation in dogs include diarrhea (often bloody), vomiting, loss of appetite, weight loss, fatigue, unkempt fur, and scooting due to itching at the anus.
As the worms multiply in the dog's intestines, they sometimes excrete the worm eggs. However, these are usually not visible to the naked eye.
Dog feces can nevertheless provide clues to a worm infestation:
- Tapeworms excrete rice-grain-like segments, which can be visible in the feces or at the anus.
- Roundworms are sometimes excreted with feces or vomit. These spaghetti-like worms are white and up to 10 centimeters long.
What helps against worms in dogs?
You can protect your dog from worms by administering deworming treatments regularly in consultation with your veterinarian. Additionally, tablets to prevent worms are available.
There are also natural remedies against worms that you can mix into their food:
- Coconut oil or coconut flakes can deter worms.
- Pumpkin seeds contain an active ingredient that can paralyze worms and help ensure they are excreted.
- Raw carrots can help remove parasites from the intestines due to their rough texture.
- Apple cider vinegar changes the pH value in the intestines, making it unattractive to worms.
In any case, ensure your dog does not eat anything while out, especially dead animals or feces.
Also, always watch for symptoms of a worm infestation and your dog's feces. If you suspect your dog might have worms, contact a veterinarian.
5. Giardia
Giardia is among the parasites that can be dangerous to dogs in the spring. These single-celled organisms occur in the environment all year round, but they multiply most strongly under moderate weather conditions, such as those that prevail in spring and autumn.
Infestation and symptoms of Giardia in dogs
Dogs can become infected with Giardia by drinking from puddles, public water bowls, or stagnant water, by coming into contact with animal feces, or by eating something while out and about.
Giardia infects the dog's small intestine and, especially in weakened dogs, seniors, or puppies, triggers recurring diarrhea, flatulence, vomiting, weight loss, and loss of appetite.
A Giardia infestation can be recognized by the dog's feces:
- The feces can be slimy, foamy, fatty, mushy, or watery. The consistency often changes.
- A yellowish to greenish discoloration is also typical.
- If the feces have a particularly foul smell, this can also indicate Giardia.
- Additionally, blood admixture, diarrhea, and occasionally firmer but mucus-covered feces may occur.
Since symptoms of Giardia sometimes only appear after some time, it is important to keep a constant eye on your dog's feces.
What can you do to protect your dog from Giardia?
The most effective protection against Giardia in dogs is mindfulness. Always be attentive when you are out and about, in the garden, and in the city, just as in nature.
Prevent your dog from drinking or eating anything outdoors – except, of course, for water and treats that you bring from home and serve in a clean bowl or from your hand.
Clean food and water bowls daily with boiling water, even if they are only used indoors. Wash dog blankets and other textiles regularly at at least 60 degrees and disinfect your dog's sleeping areas with a dog-friendly disinfectant. This way, you can prevent Giardia from accumulating and multiplying.
By feeding a grain-free diet with probiotic ingredients, you can also strengthen your dog's intestinal flora.
In the event of a Giardia infestation or for prevention, natural remedies can help in addition to chemical preparations:
- Like the aforementioned dog parasites, Giardia can also be repelled by coconut oil. Simply mix it into the food.
- Finely ground pumpkin seeds also have an antiparasitic effect and can be administered with food.
- Morosche carrot soup supports the intestinal flora and alleviates diarrhea in dogs.
- You can also give your dog small amounts of sauerkraut. This has a probiotic and intestinal-strengthening effect.
Conclusion
Parasites in the spring can be a challenge for dogs and their owners, but they should not cloud your enjoyment of the beautiful weather.
By being aware of the risks, protecting your dog preventively, and always staying vigilant, you can mitigate the dangers and enjoy the spring.
Always remember not to let your dog eat anything while out, inspect their feces, and take a close look at their coat as soon as you get home.
Also take care of yourself, as the parasites that can infest dogs in spring are sometimes transmissible to humans and can cause diseases in them as well.
One final tip: make sure your dog receives healthy, natural dog food that provides them with all the essential nutrients and strengthens their health. A strong immune system can be decisive if a parasite infestation does lead to illness.
