Logan, I am certain you can have your own pets, that way the animals get used to other dogs or cats. If I were you, I would contact your local humane society or find a rescue organization in your vicinity. Either mixed breed or purebreed. You can put a search in a search engine like golden retriever, ohio, or south carolina or wherever and they should give you listings for them. Then you can contact the site or whatever. I would imagine you have to go thru a screening process, to make sure your dogs/cats will adjust to the change in environment.
Good luck!! Keep us posted!!!
