I have noticed that Poppy is much more comfortable walking on short grass and other softer surfaces, and slows down pebbly paths. I suspect the steroids she has to take may be thinning the callouses on her paw pads to the extent that pebbles hurt, just as they do through thin shoe soles. Has anyone else noticed this? Her paws are not sore, and there is no inflammation, but the pads definitely feel smoother and softer. I don't think we will be looking at boots, though - just more walks on grass!
