Might want ' ' around the ad so it sets apart from what you are saying.

2nd verse last line has one too many syllables and is awkward to say.

Next verse has a line with the same. You may want to go through and count syllables and say poem out loud for smoothness

'Scared that I'm mean' sounds like you are mean. What about 'scared I'll be mean'?

You have good sentiment, and kept me reading. You ARE a poet. lol We all keep learning. Someone told me about a line I had that needed a syllable. I added 'and'.

I love your title and last line.

My Buddy died. I miss him very much so I understand. All but one of my dogs has been a rescue dog.
Thanks for sharing.
