I am a pet lover and the new ownere of a Kerry Blue Terrier.... I use mulch in my yard and so do some of my clients in the Kansas City North area.  I felt this important information to share to keep your pets safe.  

With the Spring season upon us, please be sure and check the contents of the mulch you are putting in your landscaping.

Checked on Snopes and it is true.   ( http://www.snopes.com/critters/crusader/cocoamulch.asp)

 Over the weekend the doting owner of two young lab mixes purchased Cocoa Mulch from local discount store to use in their garden. They loved the way it smelled and it was advertised to keep cats away from their garden. Their dog Calypso decided that the mulch smelled good enough to eat and devoured a large helping. She vomited a few times which was typical when she eats something new but wasn't acting lethargic in any way. The next day, Mom woke up and took Calypso out for her morning walk . Half way through the walk, she had a seizure and died instantly. 

Although the mulch had NO warnings printed on the label, upon further investigation on the company's website, this product is HIGHLY toxic to dogs and cats. 

Cocoa Mulch is manufactured by Hershey's, and they claim that 'It is true that studies have shown that 50% of the dogs that eat Cocoa Mulch can suffer physical harm to a variety of degrees (depending on each individual dog). However, 98% of all dogs won't eat it.' 

Cocoa Mulch, contains a lethal ingredient called ' Theobromine'. It is lethal to dogs and cats. It smells like chocolate and it really attracts dogs. They will ingest this stuff and die. Several deaths already occurred in the last 2-3 weeks. Theobromine is in all chocolate, especially dark or baker's chocolate which is toxic to dogs. Cocoa bean shells contain potentially toxic quantities of theobromine, a xanthine compound similar in effects to caffeine and theophylline. A dog that ingested a lethal quantity of garden mulch made from cacao bean shells developed severe convulsions and died 17 hours later. Analysis of the stomach contents and the ingested cacao bean shells revealed the presence of lethal amounts of theobromine.
