He is almost 10 and all of a sudden started holding his head to one side and yelping sometimes when you go to pet him. Also is trembling a lot. The vet took an X-ray and said he had an infused spine. She gave him steroids and pain meds but the steroids had him peeing and having diarrhea all over the house (even with diarrhea meds). They slowly weened him off them but we still gave him the pain meds which seemed to work then all of a sudden they didn’t seem to work anymore. They gave us a new med and he seemed better for a few weeks but now he seems to be in pain again. He just seems out of it. Kind of pacing, laying down, getting up etc....not himself. He eats fine though and still drools when he sees food and wants anything we give to him. He lost a few pounds though so the dr said to feed him an extra scoop a day which we have but last we checked he lost more weight (that could have been from a bought of diarrhea though). He was 76 lbs and as of a few weeks ago 69. We need to weigh him again. I just don’t know what else to do. I guess the next step is to check for cancer? They said his heart, kidneys, all blood tests he took last month were all normal. They also told me they loose a ton of boxers at age 7 of 8. Ours will be 10 next month. I know for a boxer that is old but some do live until 12.
