I do not have a lot of knowledge on bearded dragons as I have never kept them nor have they really ever caught my interest as far as herps go. I do not understand what the problem with some nipped or broken beard scales is as it would have absolutely no affect on the breeding potential of the animal.
The missing/broken spikes have no affect on the bearded dragon's health or breeding ability. It's merely astetics.
What I am curious on, however, is if a healthy dragon can go downhill so quickly in the span of a couple of weeks. I am not making any accusations or assumptions here, I am genuinely curious.
The runny stool can be from something as simple as different foods that he isn't used to, to parasites. My guess, is it's from too many hornworms.
The blood is likely related to cloaca trauma, from undigested bugs, which is caused by incorrect temperatures.
He received the animal on 2 October 2014. On 7 October 2014 he posted photos of loose stool from the dragon with blood in it and what appears to be undigested prey item parts. The blood does appear to be coming from the lower portions of the GI tract rather than the upper given its coloration and may simply be from the trauma of passing the undigested parts, but it is definitely signifying something is amiss in the animal's husbandry. Still, I want to know how it went bad so quickly. That is only five days.
He does state the animal ate at least five prey items (a few Dubia around 4'' each and two horns) where he later tries to claim it did not at all. In my experience with reptiles, sick ones just do not wish to eat, particularly ones suffering severe GI distress. I am also wondering just how successful a temperature gradient can be achieved in a ten gallon enclosure for an animal of that size which is where the animal was being quarantined from the beginning.
The current living conditions you described from the video I am assuming are not typically up to the beardie husbandry standards.
Can anyone post the video he posted of the dragon here? Also, is there anyone in Oregon willing to take possession of this animal and deliver a refund to Michael so it can be sent back to Karen, though, honestly, I would be concerned about shipping an animal in that state to begin with.
Can anyone request that Michael use a temperature gun to show what the temperatures in the enclosure are? Also, the types of heating elements he is using (Brand, Wattage, etc. etc.).
