These insects can be dangerous for dogs.
Many dogs and cats have a strong hunting and play instinct and try to catch anything that moves. This can be particularly dangerous in spring: With rising temperatures, more insects are active in parks and gardens – and some of them can be harmful to pets.
"Many emergencies could be avoided if people knew which insects could be dangerous," said the expert. "We urge all pet owners to keep a close eye on their dogs and cats, especially in spring and summer, and to seek veterinary help quickly if they notice severe symptoms."
Oak processionary moth: The fine, stinging hairs of oak processionary moth caterpillars can cause severe irritation in dogs and cats. Even contact with the hairs – even if the animals don't touch the caterpillar directly – can lead to swelling in the mouth area, itching, inflammation of the eyes and nose, breathing problems, severe, often bloody vomiting, and even an allergic shock with fever and lethargy.
Immediate action: Never touch the eyes after contact with caterpillar hairs. Carefully rinse dogs with plenty of water to remove loose stinging hairs; gently stroke cats' fur with a damp cloth. Rinse the mouth, nose, and eyes with lukewarm water, taking care not to spray water directly into the animal's nose. Consult a veterinarian immediately if symptoms such as facial swelling, itching, vomiting, diarrhea, or difficulty breathing occur.
Bees, wasps, and hornets: Stings from these insects are painful and can be dangerous if dogs or cats snap at them and are stung in the mouth or throat. Swelling in this area can quickly and dangerously impair breathing. Severe allergic reactions are also possible.
Immediate action: Check if the animal still has the insect in its mouth and, if so, remove it quickly. Cooling helps, but if breathing difficulties or severe swelling develop, a veterinarian must be consulted immediately – caution, this is life-threatening, every minute counts! If dogs or cats accidentally step on an insect, their paws can be cooled with ice packs or under running water. This will reduce swelling and itching. If the stinger is still embedded in the skin, it must be removed immediately, ideally with gentle, smoothing movements – do not squeeze! If the swelling does not improve, the animal should be taken to a veterinarian.
Grasshoppers and locusts: While non-poisonous, their legs have barbs that can cause injuries in the mouth. If swallowed, body parts can become lodged in the esophagus. Typical symptoms include choking, vomiting, or loss of appetite.
Immediate action: Consult a veterinary practice if the symptoms persist.
Nosferatu spider: The bite of the Nosferatu spider is similar to a wasp sting. It can lead to local swelling, pain, and redness.
Immediate action: In most cases, cooling is sufficient. However, if a dog or cat reacts strongly or shows signs of allergy, a veterinarian should be consulted immediately.
Asian lady beetle: Originally from East Asia, this beetle has spread to Germany in recent years and can secrete a yellowish defensive fluid that can be toxic to dogs and cats. If ingested, it can cause vomiting, diarrhea, or irritation of the mucous membranes.
Immediate action: Rinse the mouth and observe the animal. If symptoms persist, veterinary care is necessary.
Red ants: Red ants secrete an irritating substance, which is why their bites are very painful for dogs and cats. Swelling, redness, or small pustules often occur.
Immediate action: Cooling relieves the pain. In cases of severe reactions or known allergies, a veterinarian-recommended antihistamine may be necessary.
Stink bugs and oil beetles: These insects are not poisonous, but they release a foul-smelling defensive secretion. If dogs or cats ingest them, this can lead to salivation, nausea, or mild diarrhea.
Immediate action: The symptoms usually subside quickly. Rinsing the mouth can help.
Preventive measures
- Keep an eye on animals in the garden or in meadows. If a dog or cat suddenly vocalizes in pain or behaves unusually, check their mouth and paws.
- Do not leave food and sugary drinks uncovered in summer.
- Do not remove wasp or hornet nests yourself – hire professionals.
- If you suspect the presence of oak processionary caterpillars, immediately keep your distance and choose a different walking route.
- If your pet has known allergies, keep emergency medication on hand. Consulting your trusted veterinarian is recommended in this regard.
