It is fastidious to inject medicine into sick turtles.
Because the tortoise has a very hard carapace, once the tortoise gets sick, it is very different from other animals in treatment. Practice has proved that injection is the most effective way to give medicine to sick turtles. The following technical problems should be paid attention to when injecting turtles. 1. Never use long or thick needles. The tortoise body exposes less muscles, generally only slightly more muscles at the base of the front and rear limbs, but the area is not large. So choose a thinner and shorter needle. The injection depth is generally 0.5 cm for small turtles, 0.8 cm for medium turtles and 1.2 to 1.8 cm for big turtles.
