Sub Q Fluids for Dogs and Cats

When to Give Sub Q Fluids for Dogs and Cats

One reason to give intravenous fluids to dogs and cats is when they are sick to help prevent dehydration. Besides keeping the pet hydrated, the IV also provides a way to administer medications. Subcutaneous (Sub-Q), or under the skin, is an easy pathway to give fluids to your pets.

What Materials Are Needed to Administer Fluids in Dogs and Cats?

When administering cat or dog fluid therapy you will need the following supplies:

How to Give IV Fluids to Dog at Home

To assemble, remove the tab from the bottom of the IV bag. From the venous set, remove the cover from the larger spike end and push the spike firmly into the bag. Hold the IV solution bag up to fill the chamber, then turn off the tubing with the clamp. Attach the needle to the injection site connector. Hang the bag on a plant hook or some kind of a coat hanger. Open the clamp just long enough to purge air from the tubing and needle.

Where Do You Inject Subcutaneous Fluids in Dogs?

Holding the dog or cat, prepare the injection site. Give the injection just like any other injection, just off to the right or left of the shoulder. Have a nice distraction such as your pet’s favorite treat, so the dog or cat has something to think about besides the fluids. Adjust the proper drip rate with the clamp to administer the volume of the recommended dose according to the label.
