My 6yr old Shitzu/Lhaso mix male had a small "growth" midway on his tail that became irritating to him. In April they recommended removal with partial tail amputation,it was later found neg for cancer. He was also neutered at this time. At the time of stitch removal it came apart and we ended up having 3 more surgeries to repair and modify the incision...it has since healed with hair growth complete but it is still irritating him to the point we have to keep a bandage on it, then he calms down and rarely looks at it till the bandage comes off again. We had a second consult and they injected the incision area with lidocaine to see if it was a nerve bundle, it only made it worse! They are only recommending that we have the whole tail amputated so he will have nothing to bite at or put him on valium or such. So 5 months later after 4 surgeries,2 antibiotics,several rounds of amitriptyline,acepromazine and tramadol we still have a bandage and and misrible dog when it comes off!??!? HELP! Bubbles has a hairlip from birth, survived parvo and has been healthy untill this. His neuter incision healed well immediately...Thanks for any help!
