Hi All! My re-homed Beardie had his first vet visit this Monday and it went well. However - she found a little sore in his mouth along his gumline and decided to put him on antibiotcs (Trimethoprim Sulfa Suspension - .13ml once a day). After two doses, half of his beard turned black and stayed that way. I spoke to the vet, and she's not concerned. I just wonder what's going on. Not only that, but now that he's had 2 doses and is NOT happy about it, he won't open his mouth for me to get it in. LOL! Any thoughts/suggestions? Thanks!
