Hi again So i checked alto today, the infection doesn't move upwards, however the discoloured area has started to smell (when i put my nose close to the area). The discoloured area, as i mentioned before has started to harden, not as limp. If you could see the picture i attached earlier, at the kink (between the healthy part and the infected area), when i touched the kink part, alto whipped his tail away...i assume that part hurts him. My question...if i were to inject baytril on him at the infected area, would it be useful at this stage? Also, the baytril i could find here looks like this: µÂ¹ú°Ý¶úBaytril °ÝÓÐÀûÕë¼Á(¶÷ÅµÉ³ÐÇ)¿¹¾úÏûÑ×ÏûÑ×Ò© 1ºÁÉýÉ¢Âô-ÌÔ±¦Íø Is this the same one?
