This is my dog Sancho. He is a 5 year old Bichon Frise. He has these episodes where his back arches and he cant move. They last about 5 minutes, he is conscious the whole time and is back to normal after. Vets don’t know what is wrong but all blood work and analysis are normal. We think it might be Bichon Dyskinesia but there is very little information about this disease as it is very rare.Video Rating: 0 / 5
