No doxens
No dachshunds
No shelties (my personal favorites)

BTW: My son and I collect DOG CHIPS
He is only 11 so the dogs SHOULD be dress-code compliant and behaving.

If you have dog chips laying around... we like real dogs, fake dogs, silhouette dogs, Scooby-Doo dogs, Red Dogs, cartoon dogs, racing dogs - as long as it has an image of a dog (wolves & coyotes are pushing it but we have made some exceptions... ) - we like 'em.

ONE CATCH - we only collect CHEAP DOGS. (trade dogs - face value dogs - or inexpensive fantasy chip dogs) because of his age and his "hands on" stage of collecting.
