Cookies, candy and gum

Sweets are where the two most serious label checks live. The first is chocolate: ASPCA says it’s toxic to dogs because of methylxanthines, and the darker the chocolate, the greater the risk. The second is xylitol, a sweetener Pet Poison Helpline says can cause life-threatening low blood sugar and liver failure in dogs. It’s commonly found in gum, and one brand can use it in some flavors and not others.Everything else here is mostly sugar. Those pages say what the label lists and why a stray piece is a different situation than a whole bag.If your dog already ate something that worries you, call your vet, ASPCA Poison Control at (888) 426-4435, or Pet Poison Helpline at (855) 764-7661.
