No, hamsters shouldn’t eat dog biscuits.
These biscuits are meant for dogs. Hamsters have a very different nutritional profile than canines, and dog food just isn’t made to meet the needs of hamsters.
Many pet owners feed their hamsters crunchy foods or treat because it grinds their teeth down.
Hamsters have strong, sharp incisors that do not need grinding down. In fact, if a hamster has its incisors grind down too much, it can cause serious problems.
Dog biscuits are also typically high in protein and fat. Hamsters need a very different diet than dogs do, so these levels aren’t appropriate for them.
Most dog biscuits also have added sugar and salt which is not healthy for hamsters.
