Don't let a nosy pooch sniff around or dig up any flowers you haven't planted yourself! If Summer [1] travels take you to new parks or yards, double check that the gardens don't use cocoa mulch, a common fertilizer made from poisonous cocoa beans. Just like chocolate [2], it contains theobromine, a chemical that can cause vomiting, muscle tremors, or even death to furry friends. If you're planning your own late-blooming garden, be certain to also brush up on poisonous plants [3], and pick out some of our pet safe suggestions [4] instead.
