Respiratory infection

This is one of the most common diseases in turtles and is usually caused by a lack of vitamin A as well as poor water quality. When a turtle is suffering from this illness, its neck may get swollen and make it hard for it to retract, so it stays stretched out.

Moreover, the disease leads to the production of mucus in the eyes, nose, and mouth. This leads to wheezing and breathing difficulties, forcing your turtle to stress its neck out in an attempt to inhale more to breathe properly.

Chocking turtles stretch their necks

A choking turtle could also stretch its neck out. Turtles usually lack teeth to bite or chew food, so they gulp them down with the help of water. But sometimes the foods can present a chocking problem.

Turtles also tend to feed on gravel inside the terrarium, which can also cause a choking hazard. When this happens, the amount of air your pet is taking becomes limited, forcing them to stretch their neck to catch a breath.

Additional symptoms of a choking turtle include gasping, open-mouth breathing, frantic signs, etc. If this happens, visit a reptile vet immediately! You can also follow this CPR procedure to help your choking turtle.

Hunting for food
