I am not sure where to put this but I am going to start here. I was given a three year old Boxer, eight years ago. This dog turned out to be an amazing dog and the most loving and caring dog I have ever had the privilage of being with. I want to share what I have learned in case it will help someone else. On my first vet visit the vet she said she loved Boxers but due to their health problems she could not have another. Disconcerting but I didn't care this was a loving dog and I was going to do my best for him. When my dog got a little older the mast cell tumors started and we had many removed until a vet at a higher level of care told us there was an alternative to removing low grade mast cell tumors. Really !! Here is what is done. They inject the tumor with a steroid and believe me it works, if it does comes back again which most don't they inject it again. . I am getting ahead of myself we also learned Benadryl at a dosage of 6 pills per day three in the morning and three at night for a 100 lb dog reduced the number of mast cell tumors our dog had to the point of no more mast cells as compared to many over the years. .Why didn't anyone tell me about this before ? Then comes the joint problems with TPLO surgery being the suggested solution. My dog had the first leg done and it was an amazing success he felt great. Don't get me wrong there was a huge recovery time, Physical Threrapy and a lot of lifting a 100 lb Boxer. A few years later he had a second one done. These were both done by the same teaching hospital with an excellent reputation and I believe both were a success. Problem is after the second one my dog was never really right again his leg was getting stiffer pain meds were continued but things never got better. After some long visits to the same teaching hospital my boy was diagnosed with DM. He only lasted a few months after the dagnosis. My dog also developed Afib and we went throught the holter monitor sessions etc. The meds for this were expensive but GoodRx saved me a fortune the cost was suppose to be $325.00 for a month supply it ended up costing me $25.00 for the smae perscripotion through GoodRx. I need to tell you this dog cost me 10's of thouands of dollars over his lifetime in medical bills. I have left out many of the details and most of the emotion but I need to say.. I lost my best friend to DM and there was nothing I could do about it. When I got the diagnosis I tought we would have more time we didn't, If the things I learned help one person writing this will be worth it. Good luck with your Boxer.
