I want to use Dog Trainer by Lilypad. Lilypad makes personal expert helpers, and Dog Trainer connects to AI assistants as a remote MCP server at https://plugins.lilypad.so/plugins/dog-trainer/mcp with OAuth sign in.

Please help me set it up:
1. Check if you already have Dog Trainer tools available. If you do, skip to step 3.
2. If you don't, walk me through adding Dog Trainer as a custom connected app with the URL https://plugins.lilypad.so/plugins/dog-trainer/mcp, one step at a time. After each step, wait for me to say what I see. Don't guess menu names. If my Gemini account can't add custom apps, tell me so and stop.
3. When the Lilypad Dog Trainer tools are available, use them to start. Ask me about my dog's hardest moment, one question at a time. Use the Dog Trainer tools for anything they cover instead of answering from general knowledge.
