Study Notes

Injection Sites for Dogs

Intramuscular (IM) injection sites are located in the lumbar region (epaxial muscles) and the quadriceps.
Unacceptable IM injection sites include the semimembranosus and semitendinosus due to potential complications.
IM injections should be given with the needle at a 90° angle, penetrating through the dermis, fatty tissue, and into muscle.
Subcutaneous (SC) injections are administered in the neck scruff, with the needle pointing from caudal to cranial at a 45° angle to the skin tent.
Intravenous (IV) injections can be performed via the cephalic vein on the forelimb or the saphenous vein on the hindlimb.

Injection Sites for Cats

For cats, IM injections are primarily done in the lumbar epaxial muscles.
The semimembranosus and semitendinosus are not recommended for IM injections due to a risk of damaging the sciatic nerve.
IV injection sites are similar to dogs, utilizing the cephalic vein and saphenous vein.
SC injections in cats are also performed in the neck scruff.

Alternative Injection Sites

In uncooperative animals or if the primary injection site is injured, alternative IM sites include neck muscles or triceps.
SC injections may also be administered over the ribs or in the skin fold before the hindlimb.
Jugular vein can be accessed for IV injections but is considered a last resort due to its invasiveness.

Blood Sampling

The jugular vein is often used for blood samples because of its large size and thick walls, reducing the chance of collapse.
The lateral aspect of the ear pinna can be utilized for small blood samples, typically just a drop for glucose testing.

Safety Precautions

Before injecting, it is crucial to pull back the syringe plunger to verify the needle is not in a blood vessel, applicable for both IM and SC injections.
