Hi: I did the force feeding on the tinc. Dr. Brad wilson had given me some very intricate details on how to do it. He gave warning that doing such a thing could be so stressful as to cause death in the frog. I would only resort to it as the last possible effort. It didn't sound like you had gotten to that point. But in short, you have the right idea. I used 20 mushed FF and a tiny syringe. I wrapped him in a wet paper towel to keep him still. The credit card is what I used to open the mouth, and I had to be careful to put the syringe far back enough to ensure he swallowed. Are you making sure that in the quarrentine box you have increased humidity and temperature? I experienced my tinc going off feed from being moved as the other person suggested. If he is still dehydrated, increase water in the box and add a little pedialyte. You want to decrease as much stress as possible, give him a chance to acclamate to encourage going back onto the feeding by himself. IF not and he is beginning to be too weakened, then consider the forced feeding. I think you might find that a more positive reponse with other reptiles might be seen with forced feeding, but with frogs this size the outcome isn't always as promising. A vet, unless their experience is amphibian based and not reptile based as so many exotics are, I found was not helpful. Contact Dr. David Frye for email consult. He is most experienced with Amphibians and can offer you the right meds, fecals with photo records, and more definitive answers then our combined guesses.
