Hi dog lovers. Where is everybody? Is there another sub? The cat people are kicking butt.

Little help if you can. My neighborhood is overrun by hungry deer (and we are not allowed to hunt them 😔). I put blood meal on my landscaping to prevent them from eating all my plants but it turns out my dog loves the stuff. He keeps literally eating the mulch and dirt and the plants I flavored for him and digging like crazy too. Any suggestions for a secondary safe treatment that I can put on to keep my little stinker away from the blood meal?
