Dog Poisoning Warning

The fol­low­ing was e‑mailed to me today by an anony­mous source. I’ve vet­ted the infor­ma­tion for myself and believe it to be true and per­ti­nent to ani­mal own­ers. The fact that choco­late is poi­so­nous to dogs and cats is pub­lic knowl­edge, and numer­ous inde­pen­dent sources echo the infor­ma­tion below. Note that the quote attrib­uted to Hersheys​.com can­not be ver­i­fied because, as of the date of this writ­ing, all ref­er­ences to the HERSHEY’S Cocoa Mulch prod­uct have been removed Hersheys​.com, TheHersheyCompany​.com, and the com­pa­ny’s press release archive. However, the Hersheys​.com inter­nal seach engine reveals that, until recent­ly, it did in fact host a page describ­ing the HERSHEY’S Cocoa Mulch product.

Note that the below mes­sage includes non-specific time ref­er­ences such as “over the week­end” and “in the last 2–3 weeks”. The exact dates ref­er­enced are unknown. Independent research, how­ev­er, reveals inci­dents of ani­mal injury and death result­ing from inges­tion of the HERSHEY’S Cocoa Mulch prod­uct and sim­i­lar prod­ucts from oth­er ven­dors as ear­ly as 1998 and as recent­ly as July 2007.

The Hershey Company was not able to be reached for com­ment before press time.

It is unknown at this time how many bags of HERSHEY’S Cocoa Mulch have been sold and used. It also isn’t cur­rent­ly known if the Hershey’s Company recalled unsold units or con­tin­ues to sell them, or how many com­pet­i­tive prod­ucts remain on the mar­ket. Given the fact that the prod­uct was wide­ly dis­trib­uted by major retail chains that include Target Stores and The Home Depot stores, the risk to canids and/or felines of encoun­ter­ing and ingest­ing the poten­tial­ly poi­so­nous mulch in lawns, gar­dens, parks, and play­grounds through­out North America is almost cer­tain­ly substantial.

Please be care­ful to mon­i­tor your pets, and to be very wary of allow­ing them near mulch beds. Please also help spread aware­ness and avoid fur­ther tragedy by pass­ing around the below information.


Don’t know how many of you gar­den, but I got this from anoth­er friend and throught I would pass it on. What with gar­den­ing sea­son start­ing out, this is good infor to have.

Please tell every dog or cat own­er you know. Even if you don’t have a pet, please pass this to those who do. Over the week­end the dot­ing own­er of two young lab mix­es pur­chased Cocoa Mulch from Target 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.’

This Snopes site gives the fol­low­ing information:

Cocoa Mulch, which is sold by Home Depot, Foreman’s Garden Supply and oth­er Garden sup­ply stores, 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.
