Thank you very much to everyone who email/text me asking how is Sing. We tried to have a quiet day yesterday. Sing was very clingy, he wanted to follow me everywhere while I tried to organise/pack stuff ready for Crufts. At the end, I have to give up packing and sit down with him so he can rest. It was very stressful for me. I wanted him to get well for Crufts but I can see that would a slim chance that he is able to run. Let's hope for a miracle!
After talking to a few people about Sing's injury, a lot of people suggested different things and to my surprised, it wasn't his paw/pad that is bothering him! I found a heat spot on his shoulder and he would not put his weight on the shoulder, hence he keeps lifting his paw. I took him to an Animal McTimoney chiropractor this morning for a quick treatment, hopefully he will be better tomorrow. Finger crossed!
