Of course, I'd be happy to help you plan a surprise birthday party for your human! Here are some ideas for decorations, activities, and games to make your human's birthday special:

Decorations:
* Hang up some colorful streamers and balloons around the party area.
* Create a birthday banner that says Happy Birthday with your human's name on it.
* Put up some paw print or dog-themed decorations, like posters or cutouts.

Activities and Games:
* Set up a scavenger hunt for your human, where they have to follow clues to find their birthday present.
* Play a game of fetch with your human and their friends.
* Set up an obstacle course for your human and their friends to run through.
* Have a doggie costume contest where your human's friends dress up like different dog breeds.

Bone-Shaped Cake:
* You can order a bone-shaped cake from a pet bakery or make your own at home using a dog-friendly recipe.

Remember to keep the party safe and fun for everyone involved, and don't forget to take lots of pictures to capture the memories!
As a dog, how can I perform the decoration tasks without hands? How should I communicate, for example, to the bakery regarding the shape of cake I want, seeing that I cannot speak nor understand English?

I mean, Woof?
As a dog, it may be difficult to perform decoration tasks without hands. However, you can communicate your preferences to your human companion through body language and vocal cues. For example, you could bark or whine to indicate your excitement or enthusiasm about a particular decoration or treat.

When it comes to communicating with the bakery regarding the shape of cake you want, your human companion will need to act as a mediator. They can provide instructions to the bakery on your behalf, based on their understanding of your preferences and any previous experiences you may have had with similar treats.

If you have a particular favorite treat or decoration, your human companion can also bring it with them to show the bakery what you like. In general, it's important for your human companion to pay close attention to your body language and vocal cues to ensure that they are meeting your needs and preferences.
