I lied to my girlfriend about our dog being sick and I feel so bad and guilty

I'm the type of guy who absolutely loves being with my girlfriend, I basically geek out over anything she's keen on and we just have such an awesome time together, but I have a confession I need to make.<br><br>I recently lied to her. She bought a new puppy and I didn't want to disappoint her. I told her that I had a great idea of getting our dog into agility training as a form of exercise. She was excited to take the dog to this new activity, and I got a bit too excited and before I knew it, she was asking me to take the dog to agility training class on monday and tuesday and that's when I remembered I'm not actually signed up for the class. I didn't want to look like a bad boyfriend or disappoint her, so I lied and said that the agility training place called to postpone the class, which I knew would make me look like a great boyfriend. <br><br>I'm feeling horrible about it and I just wanted to confess here. I'll tell her the truth because she's an amazing person and I know she'll probably just laugh at my silly behavior but yeah, I just needed to get this out there.
