subcutaneous injection... My 6 year old Italian Greyhound is very sick :-( We give him 1.5 ML - 2 ML every other night from an IV bag... sometimes every night.... treating chronic renal kidney failure.
Comparison of the angles of insertion for intramuscular (IM), subcutaneous, and intradermal injections. An IM injection is given at a 72- to 90-degree angle. A subcutaneous injection is usually given at a 45-degree angle, but may be given at up to a 90-degree angle, if a short needle is used or if the person is heavy. The intradermal injection is given holding the syringe nearly parallel to the skin (10- to 15-degree angle).
