your turtle has had a limb severed due to an injury there
is not much that you can do besides allow it to heal. Usually
the turtle will be able to heal effectively on its own, just
ensure that the area is clean. Any part that is unable to
heal due to the severity of the injury will likely shirvle
up and fall off.
Turtles do not have the ability
to regrow their body parts unlike some other animals. For
example, some lizards can actually regrow
their tail if it has been severed.
The most important thing that you
can do is provide it with a clean and cool place for the first
few days to allow it to rest and begin to heal. Infections
are very common with severed limbs so keep the wound clean
at all times. The turtle will most likely be feeling a great
deal of stress after this kind of an injury so be sure to
handle it only when necessary. You will need to monitor its
activities very closely over the next few days to ensure it
is handling the situation alright.
In the future the turtle will need
to adapt to the loss of one or more of its limbs. Aquatic
turtles will have the most difficulty as they may have trouble
swimming with one less leg. In these cases you may need to
make the water shallower to ensure that it does not drown.
If the injury worsens it will be
necessary to take your turtle to a veternarian. The veterinarian
can properly dress the wound and give you advice as to how
you can ensure a smooth and swift recovery.
