Creating a playlist for your pet on Spotify is a fun and easy process. Here's how to do it:

1. Open Spotify and log in to your account.
2. Click on "Create Playlist" on the left side of the screen.
3. Name your playlist something like "Fido's Favorites" or "Whiskers' Jams".
4. Start adding songs! Think about the type of music your pet seems to respond to. Some pets might enjoy calming classical music, while others might prefer the beat of pop music. There's no right or wrong answer here, so feel free to experiment.
5. To add a song, just search for it in the search bar at the top of the screen. When you find a song you want to add, click on the three dots next to it and select "Add to Playlist". Then, select the playlist you created for your pet.

Remember, the goal is to create a playlist that your pet will enjoy, so don't be afraid to get creative with your song choices! You can also observe your pet's behavior while different types of music are playing to get an idea of what they might like.
