I learned a few years ago that mixing Baytril 9 parts sterile saline with 1 part Baytril and used to flush the nostrils works way better at getting the tortoise over a R.I. than injecting it or giving it orally. So, yes, I have heard of this.
Please give us more info. Why did you go to the vet? What are the symptoms, etc.
Any advice on how to give it to them. I tried tonight for the first time and the vet said I have to cover his eyes and when I did that he shoved his head in and made it almost impossible for me to give him the medicine
