My German Shepherd is approx 16yrs he has had a skin problem that i have treated with benzl benzoate and this has cleared it he has stopped scratching however he is constantly weeing on his bed (something he has never done) and he does not realise he has done it and remains lying in his bed also he wee's in the kitchen during the day and night regardless of going out numerous times. He is loosing his hearing and sight although he does not seem in pain could the constant wetting be something to do with his kidneys or just old age i do not want him to suffer or loose his dignity he is a beautiful old man would having him put to sleep be his only option or can he be helped
