Can puppies eat

Pistachios

?

Puppies are especially sensitive to fatty foods and pistachios can upset their developing digestive systems. Even a few nuts may lead to vomiting or diarrhea. Because puppies are curious and often chew on anything they find, pistachio shells can also present a choking risk. It is safest to avoid offering pistachios entirely and keep nut snacks stored safely out of reach in homes with young dogs

Small dogs are more likely to experience digestive upset from fatty foods like pistachios because their bodies process smaller quantities. Even a few nuts may provide more fat than their system can comfortably handle. The shells can also be a choking hazard for small breeds. Because of these risks it is best not to feed pistachios to small dogs and instead offer safer treats designed for pets

Pistachios

?

Pistachios are very high in calories and fat which makes them a poor choice for overweight dogs. Even a small handful can add a significant number of calories to a dog’s daily intake.

Dogs that need to lose weight are better off with lower calorie treats such as plain vegetables or specially formulated dog snacks
