Alcohol
Alcohol can cause
vomiting, seizure, diarrhea, decreased coordination, central nervous
system depression, difficulty breathing, tremors, coma and even death. Dogs can
even get alcohol toxicity by ingesting fermented foods if they eat enough of
it.
Bones
Don’t feed your dog
raw bones. He might choke or sustain severe injury if the bone splinters and
become lodged in or punctures your dog's digestive track.
Caffeine, chocolate and coffee
When ingested by dogs,
these can cause abnormal heart rhythm, diarrhea, excessive thirst,
hyperactivity, panting, seizure, tremors, urination, vomiting, and even death.
Note that darker chocolate is more dangerous than milk chocolate.
Citrus
Citrus contains
citric acid which can cause irritation and even central nervous system
depression if ingested in significant amounts.
Coconut products
These contain oils
that cause stomach upset or diarrhea. Coconut water contains high
concentrations of potassium and should be avoided.
Grapes and raisins
Kidney failure may
occur.
Milk and diary products
Lactose in dairy
products can cause diarrhea or other digestive problems.
Nuts
Nuts contain high
amounts of oils and fats which can cause vomiting, diarrhea and potentially pancreatitis
in dogs.
Onions, garlic and chives
These can cause
gastrointestinal irritation and can lead to red blood cell damage.
Raw meat and eggs
These can contain
Salmonella and E. coli that can be harmful to dogs. All mammals naturally have
E. coli and most are harmful. In rare instances dogs can be infected. Don’t
feed your dog raw eggs or meat. It decreases the absorption of vitamin B which
can lead to skin and coat defects.
Salty foods
Salt can cause
depression, diarrhea, excessive thirst, high temperature, seizure, tremors,
vomiting, and even death.
Xylitol
Xylitol is used as a
sweetener in numerous products, including sugar-free gum, sweets, baked goods,
mouthwash and toothpaste. It leads to vomiting, hypoglycemia (low blood sugar),
coordination difficulties, seizures and even fatal liver failure.
Yeast dough
Yeast dough can rise
and cause gas to accumulate in your dogs digestive system. These can be very
painful and can cause the stomach to bloat and potentially twist.
