SQ injections are super easy, you could definitely learn to do them. I can give them to Payton unassisted. The very first time I tried, I missed getting the needle in the skin (and got injectable B12 all over his fur!) which our vet told me I might - haven't missed since and I've gotten quicker so he doesn't even hardly mind anymore. It's not a big deal and being able to give SQ fluids is a good thing to know. When Kota was crashing my sister asked if I could give SQ fluids. I didn't know how then. I do now and I'm glad.
