if you work your dog and have them outside a lot there pads get super tough mine step on cacti all the time and it never pokes em if your doing road exercise there is a possibility they can tear that hard layer off but you just clean it up keep it bandaged for a few days with them in the crate so they don't mess it up again and they will be back up and running around fast....now if there couch potatoes they will have soft paws and you'll be fixing cut pads all the time
I love blue! All my dogs were raised on it
