the thyroid treatment was stopped due to excessive scratching of right ear causing bleeding .
The injection I am not sure what it was but was for blockage in the artery
of his left back leg making it become limp.
yes the scratching was caused by the thyroid tablets and the ointment
did not solve the problem so both were discontinued
thanks for your help.
Unfortunately he deteriorated and would not eat or drink.
The vet said he looked as if he had enough and in his opinion the massive dose of Heparin although it had helped to release the blood clot in his hind leg could have been to much for him and his system had closed down .So we had no alternative but to let him go at 18yrs and two months.
