He looks pretty close to a pure CC to me but I am new to the breed myself so I still have a lot to learn. I just did a dna test on the rescue I got that I swear is a kangal/shepherd kind of mix. Looks like we used the same company, wisdom panel. I feel like my test results were pretty off. It said that Zeus was 25% bulldog 25% white shepherd 25% german shepherd 25% mixed breed. I can see the possible shepherd in him but definitely not bulldog. They estimated that he would end up being 50-70 lbs. He is already 100 lbs and 26", very heavy boned and looks like will grow more. His temperament and other physical features don't really add up either. With that being said, I'm sure there are errors in the testing but in your case it makes some sense. If he is part Neo then he will probably be bigger than most canes. I know a lot of people are starting to mix the neo in to get a larger yet still athletic cane. I personally wouldn't mind having a slight neo mix.
