Bearded dragon poop Has red spots

Hello I have a five year old Beardie I recently switched his substrate to crushed walnut shells and have been nervous about impaction I recently noticed he hadn’t gone to the bathroom so I freaked out I looked places and it said give I’m a little bit of prune juice with olive oil and then his poop cane out with some Bright red spots on it I don’t have pictures because I didn’t really find it wearing until later he looks normal is acting normal the temperature is around 90 In the middle this is my first reptile so I’m not experienced I will send in pictures is it happens again.

Crushed walnut shells are not a good idea, or anything else that they can possibly ingest. We use paper towels for our beardie although there are other substrate materials that are relatively safe. (I'm no expert on those.)

You might want to take a sample of his poop to a good reptile vet to make sure the red spots are not blood, but there are also other relatively harmless things that can cause a red color in a bearded dragon's urate. Our beardie had the same problem and our vet looked at it under a microscope and determined that it was crystalline, not cellular, which means it wasn't blood. Best to find out for sure if you can. If not, and if he seems normal otherwise, than it's probably ok. But I hope you can get some advice from others more knowledgeable than me about good substrates.

Hi thanks for your feedback I don’t have any reptile vets near me there is one up in the cities but I don’t live there I will keep updated if it happens again I’m pretty sure its ok now
