Yorkies sometimes can get freaked out if there are two many dogs around all at once if they haven't been well socialized
it's all about getting them used to being around other dogs
Dogs ahve a specific way of greating each other
and if your dog gets to understand this "How do you do" dogwise he'll be much better in the park
get some doggy palydates under your belt before you jump headlong into the doggy pool
and have a friendlyu dog come meet you and your pup outside too
have him come over and let them smell each other
if you pup seems skiddish have the dog stay a few yards away at first and slowly bring him closer and closer
