Chihuahua deworming is divided into internal deworming and external deworming. External deworming is done once a month. It is usually preventive deworming with external drops. There are two types of medicines: sprays and drops, which are used directly outside the Chihuahua's body. Internal deworming is performed once every three months. It is basically tablet type. You need to determine the dosage according to the weight of your Chihuahua. You can just feed it directly.

What should be paid attention to when deworming Chihuahuas:

1. Deworming must be carried out only after ensuring that the Chihuahua is in good physical condition.

2. Chihuahua puppies that have just been brought home are not suitable for immediate deworming.

3. It is recommended that deworming and vaccination should not be performed at the same time, otherwise they may interact with each other and lead to vaccine failure. Generally, vaccination should be done first and then deworming.

4. Never give Chihuahuas deworming drugs used by humans.

5. If there are parasites in the Chihuahua puppies, they should first increase their nutrition and replenish their physical strength, and then deworm them.
