Rabbit not drinking / dehydrated
A rabbit that has stopped drinking, or shows signs of dehydration, needs prompt veterinary attention — urgently if it is also not eating or passing droppings. Dehydration thickens gut contents and accelerates stasis, so the two often go together and feed each other. Offer fresh water and water-rich greens, but if your rabbit refuses for several hours or seems weak, call a rabbit-savvy vet rather than waiting.

What your vet may check
Your vet may assess hydration, check for an underlying cause (dental pain, stasis, illness), and provide fluids. Rehydration is often part of treating the bigger problem.
Recovery support after veterinary assessment
On veterinary advice, daily hydration support such as WOOLY Balance Water and gentle digestion support can help maintain intake during recovery — after the vet has addressed the underlying cause.
Frequently asked questions
How quickly do rabbits get dehydrated?
Faster than many owners expect, especially in warm weather or when a rabbit has stopped eating. Because dehydration worsens gut stasis, don't wait long before calling a vet.
How can I tell if my rabbit is dehydrated?
Signs include lethargy, reduced or absent droppings, sunken eyes, and skin that stays tented when gently lifted. A vet can confirm and treat it properly.
Should I add anything to the water to encourage drinking?
Offer fresh water and water-rich leafy greens. Use rehydration or hydration-support products only on your vet's advice, and never force water into a weak rabbit's mouth.
