What kind of syringe is used to inject drugs into an animal like a hippopotamus with a hard and tough hide?

When injecting drugs into hippos, special syringes are usually used, such as pneumatic syringes or electric syringes, which can penetrate the hippo's thick skin and fat and inject the drugs directly into the skin or muscle.

In addition, to ensure the accuracy and safety of the medication, a number of preparations need to be made before the injection. First, the syringe needs to be sterilized and checked for proper functioning. Secondly, depending on the nature and dosage of the drug, the site to be injected and the mode of injection (e.g. subcutaneous, intramuscular or intravenous) are determined. Finally, the injection is carried out under the guidance of a professional to ensure that the drug does not cause harm or adverse effects to the hippo.

It should be noted that the hippo's skin is very sensitive, so when choosing a syringe, you need to select a material and model that is suitable for the hippo's skin, in order to avoid causing irritation or damage to the skin. At the same time, you need to pay attention to safety during the injection process to avoid being injured by the hippo's teeth or claws.
