When I was about 5 I saw my dog get run over by a tractor. The vet said we should think about putting him down because it could have brain damage. I threw a fit in the clinic when he said that. 
That's crazy, I can't believe your dog survived. Did you end up putting him down?
No Dobie was around when I graduated High School. That was one tough doberman. 
That's really impressive, I'm glad he was able to keep living and supporting you.
