How much milk chocolate is dangerous?
A single fun-size bar (about 0.5 oz) is rarely a problem for a Labrador but can upset a Chihuahua. Problems mostly arise with whole bars, boxes of chocolates and Easter eggs. The other worry with milk chocolate is the fat. A big binge can trigger pancreatitis 1 to 4 days later, even if the theobromine dose was low.

What to do if your dog ate milk chocolate
Note the time and keep the wrapper. Then call your vet or ASPCA Animal Poison Control at (888) 426-4435. If it was eaten within the last 2 hours and the dose is significant, your vet will likely give a medicine that makes your dog vomit. That is far safer than trying it at home. Dogs that already have symptoms may need IV fluids, heart monitoring and medication to control tremors.
