There are only a few interactive items available as of this writing, with most being available only for Crowns:

• Critter Bush - 5,000 coins
• Dog Bowl - 22 Crowns
• Dog House - 28 Crowns
• Dog Pond - 22 Crowns
• Topiary Puppy - 22 Crowns

If you're looking to spend just coins, the Critter Bush is still a cute option, as you can click on it to see your puppy jump into the bush entirely, only to chase out a critter and then jump out after it.

Technically, a new "Dog Fence" also appears in this section of the store for 1,000 coins, and it is pictured above with a dog trying to jump over it. However, we've had little luck duplicating this animation in our own Kingdoms, so perhaps this was placed here in error. Either way, it's a cute decorative option on its own, if you'd like to add a few pieces to your Kingdom.

With these new animations and Kingdom decorations, it's become even clearer that pups are here to stay. Hopefully, kittens will join them sometime soon, and will receive as much follow-up content after their release.
