💧 How to Give Your Pet Subcutaneous Fluids at Home
Why Home Fluids Matter
For pets with chronic kidney disease, cancer, or other conditions that cause mild dehydration, subcutaneous (Sub‑Q) fluids can be a lifeline. This method delivers fluids under the skin, offering hydration without repeated vet clinic visits. It’s simpler and gentler than IV therapy—and with proper instruction, caregivers can comfortably and safely administer it at home.
What You’ll Need
Essential Equipment:
A bag of isotonic fluids, usually Lactated Ringer’s
A drip set (IV line + roller clamp)
Sterile needles (20–18 gauge)
A sharps container for needle disposal (tupperware or used plastic bottle).
A sturdy hook, cabinet knob or hanger to elevate the fluid bag
Comfort tools: a large towel can especially help to “purr-ito” your cat up, lots of treats, pheromone sprays.
Step 1: Preparing the Fluid Bag & Tubing
Tear open sterile packaging, clamp/close and then insert the drip set (white sharp plastic bit into the circular opening) and hang the fluid bag about 2–3 feet (1 m) above your pet to allow gravity to assist the flow.
Fill the drip chamber (bulb) about halfway by squeezing it gently.
Prime the line by unclamping until fluid runs to the end—removing all air—then re-clamp and attach a new sterile needle.
Step 2: Administering the Fluids
Calm your pet with gentle praise, treats, or familiar blankets—many relax after a few sessions.
Make a “skin tent” by pinching up the loose skin between their shoulder blades. Keep the needle bevel facing upward and insert it parallel/45º to the spine—usually a gentle pop is felt.
Open the clamp and let the fluids flow; observe progress in the bag’s volume markers. Adjust the needle if flow stops.
Once complete, close the clamp, withdraw the needle, replace with a fresh one for next time, and apply gentle pressure to the site using a clean cloth .
Step 4: Aftercare & Monitoring
A temporary bulge under the skin is expected; this absorbs in hours—swelling that lasts beyond 24 hours time may need veterinary follow-up.
Leakage of clear or slightly blood-tinged fluid is normal.
Monitor for infection—persistent redness, heat, swelling, or discharge and reach out to your vet immediately .
Increased urination is normal development; no urination within 12 hours warrants contact with your vet.
Store fluid bags at room temperature in cool, shaded areas; discard any that are cloudy, contaminated.
Troubleshooting Common Issues
Fluid won’t flow? Ensure the bag is high enough, clamps are open, tubing is uncrushed, and the needle is still in the subcutaneous space (gently pull the needle out slightly, without removing from your pet completely; if you do, take a break and try again).
Pet won’t settle? Wrap them in a soft towel or place in a carrier or box—many feel more secure and relaxed with partial cover .
Extremely nervous about poking your pet? Practice the motion with a capped needle and you can always ask about topical numbing cream for initial sessions. Our pets’ neck skin is much looser than ours, when you pick up the skin it almost completely eliminates the possibility of stabbing muscle or bone. We’re always happy to do a demonstration in person!

A: Yes! Cats often tolerate it well, and dogs too—even large breeds—though insertion sites may vary based on skin tension .
Q: What fluid types are used?
A: Lactated Ringer’s is the standard; it’s gentle on tissues. Others may be prescribed based on health needs—never use dextrose under the skin.
Q: Is it painful for pets?
A: Most pets tolerate it well. Some may chatter or hide initially, but experience and treats typically ease their anxiety .
