Welcome to GreyTalk! Yes, I have seen this behavior when litter sisters adopted us - straight off the track. In our case, I think it was a combination of walking on cement and asphalt and the May heat here in FL that was hard on their pads. Dogs straight from the track have walked on sand for the most part.
I "conditioned" their pads by starting with short walks; literally one house at a time. Day 1 was one house and back (houses here are on 60 foot lots.). Day 2, two houses. Day 3, three and so on and so on. If there was any reluctance as the number increased, I backed off one or two and then increased again. It was tedious, but by the time the cool weather arrived (those two days in January when it's actually COLD - ), we were walking about a mile and a half.
If Rosie is "statueing", you may have to figure out what works best for her to get her attention and release her trance.
