Thank the Flying Spaghetti Monster that dogs don't have the same powers of Marvel's beloved wallcrawler / web slighter/ web head Spider Man! Imagine if they could scale up walls...there would be no place to hide the toys and treats...and I'm not even talking if they get the symbiote! That opens up a whole 'nother can of worms. Still, you may feel it needed to 'Spider Man' up your furry best friend without involving genetic tampering; might I suggest the 3/4 inch metal Spiderman Spider Sense Dog Collar Charm? It shows off some classic artwork of Spidey with his Spider Sense triggering(probably because the dog has his favorite shoe). Does not include the ring or string to attach to the collar!
