2. Onions and garlic
While onions go pretty much with anything savory, they can do more than just make your dog cry. Onion and garlic, in all forms, contain compounds sulfoxides and disulfides that are toxic to dogs if ingested. Since garlic is part of the onion family, it is even more dangerous than onion. Both can cause poisoning and damage dogs’ red blood cells that leads to anemia and sometimes a blood transfusion may be required in severe cases.
3. Macadamia nuts
Macadamia Nuts can be incredibly harmful to dogs. Macadamia contains unknown toxin but they are known to cause toxic reaction to dogs if ingested. It also can cause weakness and inability to walk, specifically in their hind legs, vomiting, hyperthermia, tremors, depression and staggering gait.
