I've had quite a bit of experience with giving shots/fluids. Dusty (my 16 yr old) will NOT take antibiotics by mouth! I can get them in her, but she gets so upset she makes herself vomit. She gets sick a few times a year and requires injections. Actually she just got a shot of ampicillin tonight, everyone else got amoxi-drops. We've also had to do subQ fluids with Dusty in the past.

Rather than type all the info out, here's a WEBSITE that has step by step instructions with pictures for each step.

Hope it helps! Good luck
