Pet day

In our school we are having a pet day for the first time, In my opinion I think that it may be chaotic because cats and dogs are meant to not get along but they can get along and etc, Im excited but I cant bring in my dog since shes a guard dog and not good with other dogs, she can be very friendly with some tho if she knows them but random dogs shes sometimes good with to, When you actually know her shes one of the friendliest dogs I know she loves visitors and has her ears down when she sees you can she knows you.
