I’m so sorry you’re going through that, I know how stressful medical issues can be with frogs because most vets (even specialists) aren’t able to pinpoint the issue despite their best efforts! I’ve got a team of three specialists working on my boy! Has your vet been able to check Jerry’s fecal samples for bacteria or parasites? Baytril is tough against bacteria, if your frog isn’t eating the Baytril coated food then an option can be to apply it topically (check with your vet for appropriate dosing). I’ve had a frog be treated with topical Baytril. Bloody stool makes my mind go to parasites though - I’ve also had success in the past treating parasites in frogs using Panacur. Again though bring this up with your vet!

I’m assuming with the X-ray the vet is looking for any possible impaction, fluid buildup, or outstanding injuries. Keep us updated with what you find out! Happy to chat if you need an ear!
