Most agility people are aware that as well as grapes and raisins, chocolate is poisonous to dogs. However, you may not be aware that cocoa shells which are used as garden mulch contain enough theobromine to kill dogs. Even if you don't have that much time to spend gardening as you are going to shows every weekend, this page could save your dog's life.
A fairly recent arrival on the gardening market is cocoa mulch. It is made from cocoa shells, a by-product of chocolate manufacturing. While this is an attractive, ecologically sound option, it is potentially fatal to dogs. Vets have reported an increasing number of deaths in dogs who really like to eat the cocoa mulch.
The mulch contains a significant quantity of theobromine, a chemical relative to caffeine, and this is the same chemical that makes chocolate toxic to dogs.
There is a small warning on the bag 'maybe harmful to animals' but not one that says it can be lethal to dogs. Please make as many people aware of this as one dog's death is one too many.
Dr. Michael Knight of the Animal Poison Center in The States said that all parts of the cocoa plant contain a compound called theobromine, a central nervous system and cardiovascular stimulant. While there are no hard numbers on just how much of the substance might be in a given batch of cocoa shell mulch, call your vet quickly if your dog is symptoms consistent with theobromine poisoning - restlessness, panting, pacing, anxious behaviour, call the vet quickly.
Knight talked about steps you can take to prevent your dogs from being poisoned in your own garden by by systemic insecticides in granular form, incorporated into the soil at the base of perennial plants along with organic fertilizing materials such as bone meal, fish meal, blood meal, feather meal or manure. All of these organic materials are very attractive to dogs, who see them as a food source.
Dr. Knight added that one needs to look at our homes through the eyes of our pets, seeking out ‘toys' and ‘entertainments' that may be harmful for them. Be prepared. If you suspect your dog has ingested something poisonous, seek medical attention immediately.
If by some happy chance you're a dog-owner who hires a professional landscaping service to care for your shrubs and other plants, be sure to get the names of all insecticides and fertilizers the landscaper has used around your plants.
