7 Yr Boxer W/ Lymphoma

I can"t believe my luck this is the second boxer I have lost to cancer,I even asked the breeders this time before we bought our brindle boxer if any health issues had been diagnosed with the parents and of course they assured me there were none.
I have had many pets in the past years and never have I loved one this much He is my best friend goes every where with our family.We even have to spell words because he knows what we are saying.Tyson was diagnosed june27 with lymphoma we have been giving him prednisone daily and 2 holistic drugs to make him comfortable.He weighed 83lbs before he got sick and now is about 110lbs. It is so sad to see him breathing so hard and so distant from us.Now his back legs and feet are swelling.I just wish I new what to expect, but then it will only worry me more.I don"t know what I am going to do when he is gone from my life.thx for listening (tyson2)
