Common Poisonous Plants Found in Hawaii

Know which plants are kapu (off limits) to your dog.

People are often surprised to learn that there are actually hundreds of plants potentially poisonous to dogs many of which could be in your home or yard, beach or forest.

ProFlowers recently created an illustrated guide to 199 of the most common poisonous household plants and flowers. The guide identifies each plant by toxicity level, shows which parts to avoid (like seeds and leaves), and indicates which plants should be kept away from pets (dogs and/or cats).  Mahalo to ProFlowers for contacting and sharing this guide with us!  http://www.proflowers.com/blog/poisonous-plants

Poisonous Foods and Beverages

Know which foods are kapu for your dog.

While it might be tempting to share your favorite grindz with your dog, check this list before giving a bite to your furry friend

  • Alcohol –  Extremely toxic, can cause vomiting and diarrhea, problems with coordination, central nervous system, difficulty breathing, tremors, coma and even death.
  • Almonds – Not easily digested by dogs. Can cause gastrointestinal irritation and distress.
  • Avocado -First, let me start with the GOOD news: Here in Hawaii, we have over 200 varieties of avocados that are safe to feed to our dogs, and many of us feed avocados (no skin or pit!) to our dogs, especially for underweight or itchy dogs with allergies (I have one dog that I have fed 3 avocados/day to, to get him to gain weight).  I have checked with several Hawaii vets, and they are all in agreement that it is safe to feed a peeled/pitted avo to our Hawaii dogs (Dogs cannot digest the skin, so they will throw it up (or try to throw it up), so it’s best to peel it), but only start with a little bit at first, to see if they have any reaction.  It works wonders! We have tons of avocado trees here, and many of our friends’ dogs here eat avocados in mass quantities and end up gaining some weight and have wonderful shiny fur coats, and they do not get sick. HOWEVER, here’s the BAD news: CERTAIN VARIETIES of Avocado contain a toxic principle known as Persin (Not all avocado varieties contain Persin!!). High concentrations of Persin are found in the leaves, bark, seeds, skin, and pits of the avocado. What varieties are toxic? Guatemalen and Mexican varieties of the avocado are toxic to animals. The Guatemalan variety, a common one found mostly in mainland stores, appears to be the MOST problematic, and the Mexican variety is the least toxic. These two strains of avocado can have different degrees of toxic potential. In dogs and cats: mild (typically vomiting and diarrhea). In other species (e.g., birds, ruminants, etc.), moderate to severe. It does cause significant weight gain in dogs, which can cause problems as they age. Pet birds should never be fed avocado, as canaries, parakeets, cockatiels and large parrots are extremely susceptible to persin toxicity. Signs of persin poisoning in birds includes the inability to perch, respiratory distress, fluid accumulation around the bird’s heart and lungs, liver and kidney failure, and acute death. My suggestion is to talk to your vet before feeding avos to your canine.

  • Chocolate – Chocolate (cocoa) is dangerous for dogs because it contains high amounts of methylxanthines, specifically one called theobromine which is toxic to dogs.
  • Coffee- Like chocolate, coffee contains methylxanthines, which can cause vomiting and diarrhea, thirst, excessive urination, seizures and even death.
  • Garlic, fresh – Can cause gastrointestinal irritation.
  • Macadamia nuts (Note: Shells are popular as yard mulch) – Can cause weakness, vomiting and tremors, but fortunately are rarely fatal if eaten in small amounts.
  • Onions – Can cause gastrointestinal irritation
  • Raisins, grapes – Can cause kidney failure in some dogs.
  • Tea – Like chocolate and coffee, caffeinated tea contains methylxanthines, which can cause vomiting, diarrhea, thirst, excessive urination, seizures and even death
  • Tomato leaves, stems – Surprisingly, the greenery of this common plant, not the tomato itself, contains solanine, a toxic ingredient that can prompt gastric upset, depression, weakness, and a decrease in heart rate.
