How to give a subcutaneous injection to your dog, step by step

Relax and seek help if necessary

You may feel a bit nervous when you first give your dog an injection, fearing it will hurt or move.

Subcutaneous injections are not complicated to administersince the subcutaneous tissue is soft and, since it does not reach the muscle, it is very unlikely that your dog will suffer pain or that complications will occur.

If you fear that your dog will move, ask a friend or family member for help, to hold your dog while you administer the injection. A relaxed environment is important for everyone involved and will keep your dog calm. If you are stressed, your dog will also be nervous.

Prepare the syringe

Sterilize the top of the jar of the medication with a cotton ball dipped in alcohol. Insert a sterile needle into the medication vial and turn the vial upside down.

Fill the syringe with the correct amount of medication.

The simplest is to extract something more than you need and then adjust the content in the syringe, pushing the excess back into the vial. This will also help expel air bubbles that can accumulate in the syringe.

When you remove the syringe, cover the needle with the protective cap and tap it a few times, to make sure you remove all air bubbles. Your vet will teach you how to do it.

Find the site where you are going to give the injection

The most suitable place to administer a subcutaneous injection to your dog is the loose skin on the neck, just above the shoulder blades or mid-back. Pinch off a piece of this loose skin using your thumb and forefinger, gently pulling up. You will see a piece of skin between your fingers, which is where you are going to prick the needle.

If the injection is insulin, it is better to use the area around the flank or belly of the dog. Ask your vet to show you how to find the right place to do it.

If you go to give injections on a regular basis, don’t always put them in the same place, since it will end up hurting. It is enough that you move the injection a few millimeters to one side or the other so that the area is not overloaded.

Administer the medication

Remove the needle guard and pierce the skin with the needle in one clean, quick motion. The needle must be inclined downwards, at an angle between 30 and 45º. It is important that you move almost parallel to the skin surfaceIf you tilt it too far, you could go through the skin and into a muscle, through it from side to side, or even into yourself.

The vet will provide you with the needles of the correct length.

Pull back on the plunger of the syringe, very slightly. If it fills with blood, it’s because you’ve touched a vein.. In this case, you will have to remove the needle and try again. If no blood comes out, push the plunger forward to empty the syringe.

remove the needle

By pushing the plunger down, the contents of the needle will be injected under your dog’s skin. When you’re done, withdraw the needle the same way you inserted it and place the protective cover, so as not to prick yourself. It is very likely that your dog will not even feel the injection or will only feel a slight sting. Once you learn how to do it, the procedure will be over in a few seconds.

Do not put your hand or finger on the plunger of the needle, because if the dog suddenly moves and pushes you, the contents will be wasted or you will accidentally inject it.

Reward your dog for good behavior.

Finally, do not throw the needle and syringe in the trash. It is better that you take them to the veterinary clinic or a pharmacy, so that they dispose of them correctly.

Never use syringes, plungers or needles that have already been used, even with the same dog and medication. In this way you will avoid infections.

What if I have to apply an intramuscular injection?

  • Intramuscular injections are administered in certain areas of the body. Are more difficult to put than subcutaneous. Therefore, if you need to do it at home, it is better that I show you your veterinarian. He’ll help you locate the proper landmarks and explain how to do it before you try it at home.
  • The first thing you have to do is maintain sterility of the vial and the needle, load the syringe with the medication and place it near where you are with the dog.
  • Once you find the injection site, use the technique your vet has told you.
  • If you have to give this injection frequently, try alternate application sitesdo not always do it in the same place.
  • To give an intramuscular injection, you have to hold the syringe in one hand and insert the sterile needle through the skin, into the underlying muscle. He needle angle should be between 45º and 90º, depending on the area. If the angle is less, it is likely that you will miss the muscle and stay subcutaneously.
  • When you have inserted the needle, pull the plunger back. If you see blood, remove the needle. and try somewhere else. If not, push the plunger forward and empty the syringe.
  • Withdraw the empty syringe, backing up the same path you used to penetrate the skin.
  • Reward your dog and dispose of used needles and syringes properly.
  • If you don’t feel comfortable giving your dog injections, ask your vet to do it for you.

Your vet will indicate the most appropriate area to apply the injection to your dog. This injection is given just under the skin and the most common places to do so are one to two centimeters from the middle of the back, near the shoulder blade or back.

Toggle application location each time, to avoid pain. If necessary, ask someone to help you restrain your dog.

Remember to hold the syringe in your dominant hand and not place your finger on the plunger until the needle is inside the skin.
