Being capable of administering sub-q or IV fluids is a very valuable tool. However like any medical treatment...there are risks. Administering fluids has saved many of our rabbits but I know how and when to administer them. Administered improperly....timing, amount, etc can be fatal. So while I am totally in favor of everyone learning how to administer fluids...it is a medical procedure that requires precautions and proper training. Have your vet or tech teach you how to administer fluids....there are different types of fluids....Lactated Ringers, Sodium Chloride, Saline, etc....and each has a purpose. There is a formula for calculating the dosage....technically it's a drug and has to be dosed properly. Learn when to give fluids....and when not to give fluids. In cases of cogestive heart failure, pneumonia type issues, head injuries and internal injuries....fluids can kill. Again, I am totally in favor of everyone learning how to do this...but like all other medical procedures...learn the correct way. This is nothing to play with....used properly, it's a life saver...but used improperly, it can be fatal.
