Valentine’s Day is right in the middle of “Chocolate season’’ from Halloween to Easter and it’s when pet poison call centers get their most calls about dogs getting sick, or in some cases dying from eating chocolate.

The darker the chocolate, the more trouble it is for dogs. Baker’s chocolate can be especially dangerous.

Even handing out a little bit of chocolate can be dangerous since it may encourage your dog to go back to raid the candy box. So, this year, be selfish and keep the candy for yourself!
