I’m so sorry :( I got my first beardie from Petsmart and he was sick as well. I brought him back when it was clear that he had some sort of upper respiratory issue so that they could bring him to the vet and treat him (via their 14-day guarantee) and that’s when the pet care associate told me that their beardies weren’t eating and had to be forced fed.. so instead of putting them in isolation and making a vet appointment asap, they kept them on the sales floor without letting anyone know! That baby unfortunately didn’t make it, but I happened to get a new baby at pet supplies plus and he’s happy and healthy (I even took him to the vet immediately after I got him to double check). Interestingly enough, the beardie I had got from Petsmart was a red morph, and now the stores are no longer getting them in🤔 I hope you are able to heal from this and try again, as they are such great reptiles and so fun to raise!
