So Disneyland allows a misbehaving dog into the park on a regular basis? It does not sound like DL follows the guideline that "service animals that are not under control can be asked to leave." This is my concern. Thank you all for your insight, it sounds like it is best for us to cancel the trip. The last thing we need is to add more out of control dog drama.
I am sorry you have had a terrible experience and don't take that lightly. It would be natural to be abundantly cautious. BUT I do think you are taking things out of context and proportion and it would be a shame to let your awful experience become debilititating enough to prevent you from visiting Disneyland. And other places. You see a lot more misbehaving pets/poorly trained service dogs out and about in regular life. At the grocery store, the mall, Starbucks... But not at Disneyland - I'm sure because it would be a big hassle to take your animal to DL without actual need. The incidences being relayed are few and far (very far) between - excepting the pink poodle who sounds like a nuisance, but not dangerous. And the aggressive dog incident was dogs reacting to anoother dog. Since you are not bringing a service animal to DL, your chances of attracting any animal's attention are minute. Truly. Of course this doesn't mean nothing could ever happen, but that's not a guantee you'll get with anything in life. So perhaps reconsider given the actual tiny, tiny chance you will even see a misbehaving dog, let alone have an encounter with one.
