Can dogs eat jam?

Standard jam is around 60 percent sugar, with a tablespoon holding about 50 calories. That is fine for people as part of breakfast but offers nothing for dogs. A dog that eats a whole jar may vomit or have diarrhea, and daily jam adds unnecessary calories.

Jam on toast crusts is a common way dogs get it.

Grape jelly and grape jam are made from grapes or grape juice, and grapes can cause kidney injury in dogs. The exact toxic amount is unknown, and some dogs react to small quantities. Treat any grape product exposure as a reason to call your vet.

Mixed fruit jams and preserves may also include grapes or raisins.

Reduced-sugar and diabetic jams replace some sugar with sweeteners. Most use stevia or sucralose, but some contain xylitol. Read the ingredient list carefully and look for xylitol or birch sugar.

Jam-filled pastries and biscuits may also be made with sugar substitutes.

If your dog enjoys fruit flavors, a few pieces of fresh dog-safe fruit are a better choice than jam. Small pieces of plain toast without spread are fine as an occasional shared crust. Store jam jars with lids firmly closed, and wash the knife before putting it in the sink, since sticky knives left on low draining boards can cut a dog's tongue. Crumbs on the breakfast table are not a concern as long as the jam was an ordinary fruit variety.
