I came home today and my hubby and daughter told me her foot was sore. I went out and my daughter held her and I looked at her foot real well. I couldn't see anything wrong with it visually. Our dog run which they run through to get to the back has some 3/4" gravel and the back yard now consists on dead weeds, burrs. There are no goat head type stickers at all, hubby takes care them right away! She does run on it but when she gets where she is going she will stand on one leg. Here are pics on what I got, hope they help. We can use any help we can get.
