Ok got a second opinion. For sure it's cystine crystals. The vet said there isn't a way to test for cystinuria but that they(the crystals) are rare to have(without the disease) and there is prob a good bet he has it. She said that neutering wouldn't affect it one way or the other, that it was more of a preventative measure so as to not breed pups that could have the disease or be carriers of the gene.
I guess the next step is to have an x ray and/or ultrasound done to see if there is a presence of stones in the bladder or kidneys. Not all stones can be seen in either one or the other and sometimes both.
Both vets said basically that there are two ways people try and manage the disease, diet and medication. Hills U/D is an ultra low protein diet that also alkalinizes the urine. But there is mixed information whether this actually works or not to prevent stones from forming and it's also $75 for a 27.5lb bag. Also apparently it can also cause other types of stones to form that only form in alkalinized urine. There is also some debate as to whether an ultra low protein diet is even healthy for large breed dogs. The other option is something called Thiola but is apparently very expensive for large breed dogs and can have adverse side effects. The vet said she was going to research the data a little more and let me know her findings. I found an article that talk about this subject a little more in case anyone wants to read more about this
