Twas taught to play with a dog's paws daily from the moment they're brought home when I took my dog through obedience training. We were also shown how to check their teeth, mess with their ears and do a basic physical exam to desensitize the mutt to being handled by a vet. Even though I run my dog (on blacktop & concrete) 5~6 miles a day 4~5 times a week during the summer I still need to keep her nails trimmed.
