We discovered he had a bone tumor located in the back of his left nostril. Unfortunately it was in the worst place to have it as they could not remove it, it's to close to the brain. It came up benign, but if would continue to grow it would grow into his brain and eventually, well you know the rest. So he has to go through 19 radiation treatments. These Vets that do them are not close either. There are only 3 in Illinois and I guess we are lucky it is only 40 miles each way. some people we have met come a long way to treat their animals here. They know their stuff too. We are in good hands. Real side effects don't show up until 2-3 weeks. That is also when we should start to see some improvement. We pray we do. They are very much confident.
