Fluid therapy restores and maintains hydration in pets who are dehydrated, vomiting, not eating, recovering from surgery or living with kidney disease.

Fluids can be given intravenously (IV) in the hospital or under the skin (subcutaneously). For some pets with ongoing needs, your vet may discuss whether fluids can be given at home.

Signs Your Pet May Be Dehydrated

Dehydration can develop quickly, especially in small, young or older pets and in those with vomiting, diarrhea, fever or a poor appetite. Hot weather and chronic conditions such as kidney disease or diabetes can also make it more likely. Check your pet's gums and energy level if they seem unwell. Watch for these signs, and call us or come in right away if your pet seems weak or can't keep water down:

  • Dry or sticky gums
  • Sunken eyes
  • Skin that is slow to fall back into place when gently lifted
  • Lethargy or weakness
  • Loss of appetite
  • Reduced urination or dark, concentrated urine
  • Thick saliva or panting when your pet hasn't been active

Giving Subcutaneous Fluids to Your Pet at Home

Some pets, especially cats with kidney disease, benefit from regular fluids given under the skin at home. It can sound intimidating, but many owners find it becomes a calm, quick part of the routine. Your vet can explain how home fluids are set up and given, and how to help your pet stay relaxed.

A few tips help things go smoothly. Choose a quiet, comfortable spot and the same time each day. Warming the fluid bag slightly to body temperature can make it more comfortable. Offer treats or gentle petting, and ask a family member to help if needed. Always follow your vet's instructions on amount and frequency, and let us know if you notice swelling that doesn't go down, redness or changes in your pet's energy.

Fluid Therapy: Frequently Asked Questions

Does fluid therapy hurt my pet?
Most pets tolerate fluids well. Placing an IV catheter or a needle under the skin causes brief discomfort, similar to a vaccine. Many pets feel noticeably better once they are rehydrated, which helps them stay calm during later treatments.
What is the difference between IV and subcutaneous fluids?
IV fluids go directly into a vein and act quickly, so they are used for sicker pets who need close monitoring in the hospital. Subcutaneous fluids are given under the skin and absorbed over several hours, which works well for mild dehydration and ongoing care at home.
Is it normal for a lump to form after subcutaneous fluids?
Yes. A soft, squishy pocket of fluid under the skin is normal and usually absorbs within several hours. Sometimes fluid shifts down toward a leg or the belly. Call us if the area becomes hard, hot, painful or still hasn't gone down by the next day.
Can fluid therapy help cats with kidney disease?
Often, yes. Cats with chronic kidney disease tend to lose more water through their urine, and regular fluids can help them stay hydrated, feel better and eat more comfortably. Your vet will recommend an amount and schedule based on your cat's bloodwork and condition.
