My heart goes out to you, brother and I sure do feel ya'. I live a life of perpetual terror that anything should ever happen to my beloved Jerry.
My thoughts and prayers are surely with you and Brutus. Glad you caught it early and I'm certain he'll pull through. It's a good sign that the vet took him in for treatment. If his condition were questionable, it's doubtful they would have.
All the best brother and stay strong.
