Pet owners attach great importance to vaccinating their pets, but they neglect deworming because the cat doesn’t go out or they don’t see bugs on the pet, so they think deworming is unnecessary. In fact, this idea is wrong. "Vaccine" and "deworming" are indispensable. Next, the editor will tell you about the deworming medicines for pets. Let’s have a good time together!

Common deworming drugs for pets are divided into internal deworming, external deworming and simultaneous internal and external deworming. Pet owners can choose appropriate deworming drugs for their pets based on factors such as their pet’s age, weight, living environment, and feeding habits.

1. Internal anthelmintics

1. Quanxinbao

Quanxinbao is an internal anthelmintic drug for dogs. It mainly has a good removal effect on common internal parasites such as roundworms and tapeworms, and has a good preventive effect on heartworm and lungworm. However, when using Canine Heart Protection, you need to pay attention to the following points: First, because its main ingredient is ivermectin, it cannot be used on collies such as German Shepherds and Scottish Shepherds, otherwise it will cause poisoning in such dogs. Secondly, if the dog is already infected with heartworms, it is not recommended to use this drug, otherwise it will stimulate the heartworms and worsen the condition.

2. Baichongqing

Baichongqing is a broad-spectrum anthelmintic drug. It is mainly used to treat nematode and tapeworm infections in pet dogs and cats. It can effectively kill tapeworms, roundworms, and hookworms in dogs and cats, and kill whipworms in dogs.

2. External anthelmintic drugs

1. Fulian

Fulian is an external anthelmintic drug for pets. It can effectively kill and prevent external parasites such as fleas and ticks. It is recommended that deworming be done once a month for young pets. For adults, pets can choose the appropriate deworming frequency according to environmental changes. For example, when the ambient temperature is high, deworming can be done once every 1-2 months. At the same time, Fulin needs to be dropped on the parts of the pet that cannot be licked, such as the head, neck, back, etc. If the pet's external parasite infection is serious, systemic administration is usually required. At this time, it is recommended that the pet wear an Elizabethan collar.

2. Nicotine

Nicotine is an in vitro anthelmintic drug. The main active ingredient of Nicotine is aforana, which is taken orally to remove external parasites such as ticks and fleas on dogs. When feeding a dog, the dosage needs to be determined based on the drug instructions and the dog's weight. Overfeeding may cause drug poisoning in the dog. In addition, external parasites are highly contagious, and the environment in which dogs live needs to be thoroughly disinfected.

3. Deworming both internally and externally

1. AiWalk

The main ingredients of AiWalk are imidacloprid and moxidectin, which are mainly used to treat ear mites, fleas, roundworms, hookworms and heartworms. The pharmaceutical ingredients can deworm both internal and external at the same time. Due to the ingredients of the drug, when using Aiwalker on your pet, it is recommended to drop it on the neck as much as possible to avoid licking it and causing drug poisoning.
