I dont have any other dog but I know when I take Gracie to the doggie park and there are labs and other bigger dogs... Gracie will get scared if they all come up to sniff her at once... but if its just one she will let them sniff and be submissive to them... but Gracie is not use to other dogs here since she is the only child! lol I have seen alot of other people on here that have bigger dogs... that their babies get along GREAT!!! I see that the bigger dogs think that our little yorkies are their pups... its really cute to see some of the videos on here...
