Are Cedar Chips Toxic if Ingested by a Dog?

According to this link, cedar chips aren't toxic: http://www.gardenguides.com/90209-cedar-mulch-dogs.html
But, and it's a big but, they can cause vomiting and/or loose stools, and because they're usually cut in fair-sized chips, they can cause intestinal blockages.

I'd swing by the vet ASAP just to be on the safe side.
Mulch that is immediately toxic is cocoa mulch, it contains theobromide, the same stuff that's in cocoa and makes chocolate an unsafe substance for dogs to eat.

Go to the Hospital ASAP! Cedar Chips are toxic. Also, there are foreign objects in your dog's system.

I am jot sure about the toxicity of cedar chips, but your dog cannot digest wood. You should see your vet right away.

I would recommend checking out the ASPCA website for toxic and non toxic plants to animals.
