Many frenchie owners use or have used #4 and #9. We recommend you talk to your vet about any concerns you may have.

1. Chocolate: Dark equals dangerous! Bakers and dark chocolate are the most toxic, and milk chocolate if ingested in large amounts.
2. Xylitol: This sweetener found in sugarless chewing gum and candy, medications and nasal sprays causes a rapid drop in blood sugar and liver failure only in dogs (not cats).
3. NSAIDs: Ibuprofen, naproxen, etc., found in products like Advil, Motrin, and Aleve. Dogs don’t metabolize these drugs well; ingestions result in stomach ulcers and kidney failure.
4. Over the counter cough, cold and allergy medications: Those that contain acetaminophen or decongestants, such as pseudoephedrine or phenylephrine, are particularly toxic.
5. Rodenticides (mouse poison): These may cause internal bleeding (brodifacoum, bromadiolone, etc.) or brain swelling (bromethalin), even in small amounts.
6. Grapes and raisins: These harmless human foods cause kidney damage in dogs.
7. Insect bait stations: These rarely cause poisoning in dogs – the bigger risk is bowel obstruction when dogs swallow the plastic casing.
8. Prescription ADD/ADHD medications: These amphetamines such as Adderall, Concerta, Dexedrine, and Vyvanse can cause tremors, seizures, cardiac problems and death in pets.
9. Glucosamine joint supplements: Overdose of tasty products such as Cosequin and Move Free typically only cause diarrhea; however, in rare cases, liver failure can develop.
10. Silica gel packets and oxygen absorbers: Silica gel packs, found in new shoes, purses or backpacks, is rarely a concern. The real threats are the iron-containing oxygen absorbers found in food packages like beef jerky or pet treats, which can cause iron poisoning.
