Today my dog was limping. I figured it was his hips/getting old and was a sad about it. After a whole day of not acting like himself he sat down and started digging at his paw. I sat next to him and had a look. I pulled a thorn out of his paw that ws about 1/2 inch long. The dance he did when I pulled it out, the kisses I received and his sudden change in attitude, made me so happy. IMMD
