In my Thoughts
You and Junior are in my thoughts. I certainly hope for the best for Junior. He looks much like my Fred.
My Fred had 3 mast cell tumours removed without any problems whatsoever, with exception for some very minor scars where the incision was made. They were never deep, since I understand that most mast cells extend outward and fingerlike. I understand from my Vet, who has a Boxer who has had 4 mast cells himself before age 4, that for some reason a Boxer can sustain a mast cell unlike other dogs. Kind of like, get them removed, and move on. I myself had Fred's first tumour biopsyed, came back grade 1. However, I never did have a biopsy of the second and third. I figured they were no different. Just get them off fast. And he survived them just fine. Although he was laid to rest this week from a mass in his stomach, long after the last mast cell he had, I do not beleive it is connected to the mast cells for certain, but I will learn more next week. So there is plenty of hope for Junior. Of course you will enjoy him, and keep a close eye on his health. Best wishes.
