Sheep very lame on front foot, she was turning it under her rather than walking on it. We penned her in and found a small round sore patch underneath sort of on the edge of where her foot is split. I have been bathing it daily in hibiscrub and spraying with tetcin from the vet for over a week now and it is much more comfortable for her, she is walking on it now but it is still red and sore looking and today I noticed her hoof seems to be coming apart in a wider ring round the sore patch. Her hoof is quite soft I assume because of my soaking it everyday. Should I be getting the vet to come?
