I think its fine to have dogs wear shoes. Slade has pair, and I'm ordering Laney a pair b/c last year when we went on a walk a few hrs afterward she ended up getting violently ill. We finally figured out it was b/c someone in the neighborhood had but fertilizer or weed killer on the grass and she had stepped in it and licked her paws.
I don't want my baby ever to get those nasty chems in her tummy again. I keep her off peoples main lawns, but some ppl fertilzie or put weed eater aroudn their mailboxes and ditches too.
