Hello caspersmom!
Welcome to the forum & congradulations on the Maltese [one of my other top favorite toy breeds]. I am a Pomeranian owner & lover; I take my little girl "Kayla" with me everywhere I possibly can.
The catch is... you can't take them inside. I have attempted to bring her places but there will be signs everywhere stating that only working dogs for the blind, deaf, etc are allowed. I have seen some people with their tiny dogs in the mall in their purse (I have tried this but been caught and told to leave).
I live in MASSACHUSETTS and I know for a fact around here they are no "dog friendly" places unless it is PETSMART or PETCO.
If you move to FRANCE they allow dogs everywhere! :o) Pretty cool huh?
I know a lot of people who take their toy dogs everywhere in their purse or in stroller and don't get caught. But that's just it, try not to get caught, b/c its the law not to bring them places. If you think about it... when it comes to resturants it makes sense. And most dogs are not potty trained so its just a health hazard.
My Pom loves car rides and I'll bring her everywhere with me if I won't be away from the car more than 30mins.
I would do a local search to see what's legal and where you take take him...
Enjoy him! Toy breeds are the best! *hugs*
