In the process of raising pet dogs, I believe many poop owners know that when dogs have worms in their bodies, it is easy to cause diarrhea. But why do owners keep scratching their dogs after deworming them? So what’s the best way to deal with a dog that keeps scratching after deworming? In fact, there are several reasons, let’s take a look below!

1. The anthelmintic medicine has not yet taken effect

Dog deworming requires a process. Ordinary external anthelmintics usually kill fleas within 24 hours and kill ticks within 48 hours. Therefore, during this period, the dog will still be itchy and cannot help scratching. Therefore, it is recommended that the owner wait patiently for a day and wear an Elizabethan ring on the dog to prevent the dog from scratching.

2. Allergy to deworming drugs

If the dog is still scratching after a period of time after deworming, it may be that the dog's skin is allergic to the deworming drug. At this time, it is recommended that the owner immediately stop using the anthelmintics and take the dog to the pet hospital for desensitization injections. This will be more effective. Otherwise, the dog will keep scratching and the skin will be scratched. At the same time, it also shows that this anthelmintic is not suitable for dogs and cannot be used next time. Other anthelmintics need to be replaced.

Note: The anthelmintics used for dogs must be produced by regular manufacturers. Do not buy pet-specific medicines casually. When using, you must also choose the appropriate dose of anthelmintic according to the instructions and the dog's weight to avoid causing harm to the dog.
