Rhubarb causes hypersalivation, tremors, and kidney failure, according to Edwards.
Tomato plants can lead to solanine toxicity, with side effects such as hypersalivation, anorexia, severe gastrointestinal upset, diarrhea, lethargy, central nervous system depression, confusion, behavioral change, weakness, dilated pupils, and slow heart rate.
Even small doses of citrus fruits like oranges can cause upset stomachs in dogs. Larger doses can cause increased stomach pain and potentially depression of the central nervous system.
Many people know chocolate is bad for canines, but in addition to vomiting and diarrhea, the methylxanthines in the chocolate can lead to heavy panting, excessive thirst and urination, hyperactivity, abnormal heart rhythm, tremors, seizures, and death.
"Darker chocolate is more dangerous than milk and white chocolate as it contains a higher amount of methylxanthines," explained Goldstein.
Coffee and caffeine
Just like chocolate, coffee and caffeine both contain methylxanthines, which can cause the same symptoms as chocolate.
Though your dog probably isn't drinking coffee with you, be wary of where you keep beans in your pantry.
Uncooked eggs can cause skin and coat problems for your pet. There's also obviously the potential for Salmonella and E. coli exposure.
Milk and dairy
"People and cats are really the only mammals that can tolerate milk as adults," Goldstein said. Dogs have a low amount of lactase and have trouble breaking down lactose efficiently, which can cause upset stomachs and diarrhea.
Potato leaves, stems, skin, or any green parts
Potato leaves and stems can cause vomiting, diarrhea, anorexia, disorientation, lethargy, and central nervous system depression.
The skin can cause vomiting, diarrhea, lethargy, tremors, seizures, and cardiac arrhythmias.
Peach stems, leaves, and pits
These can cause symptoms in your dog like dilated pupils, bright red mucous membranes, difficulty breathing, shock, and even death because they contain cyanide.
"The dilute nutraceutical extracts can have anti-inflammatory effects, but large amounts of licorice can cause muscle damage and adrenal gland issues [for your dog]," Edwards said.
