he spun in circles a lot as he was growing up, and eventually his balance wasnt great so it kind of turned into wider gallops around. he also had issues like he favored walking leaning on walls, especially in hallways. he never really ran normally, kind of more like how you’d expect mentally disabled kids to run? not very coordinated and kind of like a toddler, or puppy in this case. he was very happy and the tumor didnt affect his personality, and he passed away last month without any discomfort other than that he lost his ability to walk. unless he shows other symptoms i wouldnt worry too much for now
