WARNING TO ALL DOG OWNERS

I didn't know this but.... never ever give chocolate to dogs as it's like poison to them. My mum and dad's Jack Russell 1year old puppy has been in vet hospital (taken by vet ambulance last night) on a drip with pancreatis caused by eating chocolate!! They hope she'll be ok but the vet said never ever give them chocolate. Never heard of it before and we've been dog owners for 30+ years. So beware.
