My boxer has already been diagnosed with peloric stenosis of the intestines and he now has dime size tumors breaking out on his legs and trunk. Every article I read state that mass cell tumors are common among boxers but there is no cure and they can turn to cancer. Has anyone had experience with this? My baby is only 1 1/2 and he has had nothing but problems. Both of these conditions are genetic. Thanks for any help you can give.
