Side Effects of Dog Deworming Medicine

Dog deworming medicines can be divided into internal and external types. The side effects of external dewormers are mainly manifested on the dog's body surface, which usually causes symptoms such as hair loss, red spots, and dandruff. If the residual medicine is licked by the dog, it can cause vomiting, diarrhea, or liver and kidney damage. The side effects of internal dewormers are mainly reflected in the dog's digestive system, usually caused by overdose, and manifest as vomiting, diarrhea, loss of appetite, and lethargy. If a dog experiences particularly strong side effects due to deworming, it is recommended to seek medical treatment immediately.

The side effects of different deworming medicines vary. When giving dogs deworming medicine, owners can beforehand consult with doctors or search online to learn about the possible side effects and correct coping methods.

External Deworming

External dewormers are usually in the form of topical drops. If the drop location is incorrect and the dog licks the residual medicine, poisoning may occur. Clinical symptoms usually include vomiting, diarrhea, and liver and kidney damage.

Moreover, depending on the specific drug, if sulfadimidine is used, the main adverse reactions include inflammatory or non-inflammatory hair loss at the application site, as well as vomiting, drooling, and diarrhea. If the drug used is permethrin, the main adverse reactions include desquamation, hair loss, itching, and erythema due to allergic dermatitis at the application site.

Internal Deworming

The common ingredients in internal deworming medicines are abamectin and pyrantel. If the dog's weight is not properly considered during deworming and the medicine is overused, poisoning may occur. This side effect is usually manifested in the dog's digestive system, with symptoms such as vomiting, diarrhea, decreased appetite, and lethargy.
