It's me again everyone....I'm 24/7 on this site.

I took Snickers to a doggy friendly outdoor mall yesterday and this morning I looked at his cute little pads on his paws and noticed a little pink coming through. I am not sure if the snowy pathways or salty pathways for that matter have taken toll on his paw pads. Is this normal?? Do any of you have boots/shoes for your pups? Where did you get them? Do your pups like them or wiggle/bite them off? Expensive? I think I should get Snick some since I do like to walk him even in snowy weather.
Thanks
